fix: Change test output formatting from code to html

[ojeytonwilliams]

• I have read freeCodeCamp's contribution guidelines.
• My pull request has a descriptive title (not a vague title like Update index.md)
• My pull request targets the master branch of freeCodeCamp.
• None of my changes are plagiarized from another source without proper attribution.
• All the files I changed are in the same world language (for example: only English changes, or only Chinese changes, etc.)
• My changes do not use shortened URLs or affiliate links.

This replaces the Output Monaco editor with a pre element and adds a little css. The idea being to highlight the output the same way as the TestSuite in the SidePanel, rather than treating it as JavaScript.

I thought it would be best to sanitize the output, because arbitrary output is possible via console logs. Finally, I removed <base href='/' /> because it did not seem to be doing anything!

Closes #35800 , closes #17925 and closes #35811

hey @ojeytonwilliams can you please fixup up the lock files and package files. I seem to have created a conflict by merging the npm install PR. Thanks.

@raisedadead Sure. Turns out santize-html was already being used.

Current beta:

You can see the <strong> tags there
and the text turns to red after the apostrophe in element's

Looks good to me @ojeytonwilliams.
