MLH fellowship - batch 2

[slorber]

💥 Proposal

As new MLH fellowship interns will join us, here is a list of possible tasks that they could handle:

• CodeSandbox template + create docusaurus.new domain ([v2] Proposal: Official CodeSandbox Template #1699)
• Social cards: sharing the link of a Docusaurus based site should make the link "attractive" with to a social card(RFC: social cards #2968)
• Build Size Bot: add tooling to track perf regressions in PRs (bundle sizes, load time...) ( CI: detect perf/size regressions (build size bot, lighthouse...) #3521)
• Improve Docusaurus init templates (Improve the initial templates #4079)
• Theme gallery: improve bootstrap theme, create tailwind theme, and a shared utils package (Theme gallery #3522)
• Theme integration tests: (Theme integration test suite #3523)
• Migration: improve the v1->v2 automated migration tooling (Improve migration CLI #3520)
• Help migrate major sites like ReactNative (in progress) and Jest (Migrate Jest site to Docusaurus v2 #3524)
• Keyboard shortcuts (RFC: Keyboard Shortcuts #3020)
• Translate Docusaurus v2 website to your own language (Help us translate the Docusaurus 2 website #3526)
• Make a docusaurus site more usable without any JS (Make site usable without any JavaScript #3030)
• Detech broken anchor links (Detect broken anchor links #3321)

Note, some issues come from the meta-issue we had for MLH batch 1: #2267
