refactor(docs): replace component-docs with docusaurus

[andrewtsar0w]

Summary

This PR replaces component-docs with docusaurus for documentation since other modern OSS projects are using it.

Test plan

TBD

Todo

• [x] Initialize new docs site (using docusaurus)
• [x] Write custom plugin that utilizes component-docs’s parser to parse components' description and props (using this approach we won't need to do any changes to existing components docs)
• [x] Fix: components categories structure does not match previous docs version
• [x] Fix: icons preview on the Icons page
• [x] Fix: component props table (better styling and references support like in the previous docs version)
• [x] Configure homepage
• [ ] Get the new site reviewed
• [ ] Actualize guides pages with the latest changes
• [ ] Update internal links the docs/pages
• [ ] Remove old docs site (using component-docs) (it might be done as the latest step to reduce the potential merge conflicts)
