[Add Feature] View docs in a more comfortable way

[ryankert01]

Description

When I'm reading the documentation, I felt a bit uncomfortable when traveling between files. So I think I can change that by using a static website generator. In this case, I pick vitepress, which is a framework that specifies with writing documentation on various Github Projects.

You can see the final work on : https://ryankert01.github.io/Catch2/

I think it is pretty nice with the look and the experience and can potentially attract more users.

I think you may want to update the .gitignore !

e.g. docs/dist/ and node_modules

[ryankert01]

updated that

[adehad]

Nice, don't forget to remove the files currently committed in those locations. That should remove around 1million lines from this pull request!

[ryankert01]

deleted node_modules and docs/.vitepress/dist

There is also #2672 competing for this, and I believe sphinx is more standard. Want to discuss this in #2709 ?
