feat: initial rewrite of the exercise

[FidelusAleksander]

This pull request updates the GitHub Skills Dad Jokes action course to use a modern, bundled JavaScript action structure with improved, step-by-step instructions. The changes guide learners through setting up a cloud-based development environment, writing modular source files, bundling the action, defining metadata, and creating a workflow to run and consume the action output. The instructions are clearer, more practical, and aligned with current best practices for GitHub Actions.

Course Content and Instructional Improvements:

• Step 1 (1-step.md): Rewritten to emphasize using GitHub Codespaces for setup, initializing the Node.js project, installing dependencies, and ensuring node_modules/ is excluded from version control.
• Step 2 (2-step.md): Guides the learner to create modular source files (src/joke.js, src/main.js), run the action locally, and optionally debug using @github/local-action and VS Code launch configuration.

Action Packaging and Metadata:

• Step 3 (3-step.md): Adds instructions to bundle the action using @vercel/ncc, updating package.json with a build script and generating a dist/index.js file for distribution.
• Step 4 (4-step.md): Introduces creating a top-level action.yml referencing the bundled output, defining the action’s interface (name, description, outputs, runtime, main entry).

Workflow Integration:

• Step 5 (5-step.md): Provides a workflow example that triggers on issue comments, runs the Dad Jokes action, and posts the joke as a comment using the output.

Cleanup and Minor Changes:

• Removes unused or placeholder files (-step.txt, 0-welcome.md). [1] [2]

These updates make the course more engaging and practical, ensuring learners follow current standards for building, packaging, and using JavaScript GitHub Actions.

Pull Request Overview

This PR modernizes the GitHub Skills Dad Jokes action course by transitioning from a local .github/actions/ structure to a bundled, top-level JavaScript action following current best practices. The updates provide clearer step-by-step instructions that guide learners through setting up a cloud-based development environment, writing modular source files, bundling with @vercel/ncc, defining action metadata, and creating a workflow that consumes action outputs.

• Rewrites all step files to align with modern JavaScript action development patterns
• Updates validation workflows to check for new file locations and bundled output
• Removes unused placeholder files
