Programming exercises: Fix overflowing content for exercises with UML diagrams

[rabeatwork]

Checklist

General

• This is a small issue that I tested locally and was confirmed by another developer on a test server.
• Language: I followed the guidelines for inclusive, diversity-sensitive, and appreciative language.
• I chose a title conforming to the naming conventions for pull requests.

Client

• Important: I implemented the changes with a very good performance, prevented too many (unnecessary) REST calls and made sure the UI is responsive, even with large data.
• I strictly followed the client coding and design guidelines.
• I added multiple screenshots/screencasts of my UI changes.

Walkthrough

The recent update involves refining the user interface and style consistency of the web application. It focuses on improving the display behavior of UI components by introducing flexible wrapping and ensuring images within specific elements have a constrained maximum width. These changes aim to enhance the visual presentation and user experience of the application.

Changes

File Path	Change Summary
.../course-exercise-details.component.html	Added flex-wrap class to improve display behavior.
src/main/webapp/content/scss/global.scss	Set images in elements with IDs starting with 'plantUml-' to have max-width: 100%; for better width management.
.../exercise-update-plagiarism.component.spec.ts	Updated handling of fieldCPCEnabled access, valueChanges triggering, and validation logic in the Exercise Update Plagiarism Component test.

Possibly related issues

• Exam mode: The diff for problem statement changes is broken if inside Markdown structures #7793: The changes in this PR indirectly align with the objectives of ensuring consistent rendering across different sections and browsers. By enhancing UI responsiveness and visual clarity, these changes may help address issues with diff views and HTML rendering within code blocks, contributing to a more stable layout.
• UX(Excercises): Text too wide #7648: The modifications related to setting a max-width for better readability in the task description could be indirectly impacted by the UI improvements made in this PR, potentially enhancing the overall user experience in reading long tasks.

Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

CodeRabbit Commands (invoked as PR comments)

• @coderabbitai pause to pause the reviews on a PR.
• @coderabbitai resume to resume the paused reviews.
• @coderabbitai review to trigger a review. This is useful when automatic reviews are disabled for the repository.
• @coderabbitai resolve resolve all the CodeRabbit review comments.
• @coderabbitai help to get help.

Additionally, you can add @coderabbitai ignore anywhere in the PR description to prevent this PR from being reviewed.

CodeRabbit Configration File (.coderabbit.yaml)

• You can programmatically configure CodeRabbit by adding a .coderabbit.yaml file to the root of your repository.

Thank you for this fix, tested on ts2, works as expected (code also looks good)!
Gone are the days of 5 scrollbars on the exercise view 🥰
