Configurable syntax highlighting languages

[bravo-kernel]

I am creating this ticket for v2 after discussing with @endiliey to start the discussion (ping @langpavel).

🚀 Feature

Extend docusaurus.config.js so users can easily add/remove prismjs syntax highlighting languages.

Motivation

Currently:

• docusaurus ships with a hard-coded set of 32 languages (out of 192) enforced by prism-react-renderer
• the solution makes it hard to add additional languages, see:
  • install prismjs package
  • swizzle CodeBlock component
  • update code as described in these docs

Pitch

Should be implemented so that:

• Docusaurus can be used for documenting all-the-things
• the Docusaurus project can control the list of default languages, possibly even decreasing the default bundle size

Pre-discussed

The solution could be something like:

• add prismjs to package.json
• only add languages that are present in the configuration file to the build/bundle
• because the CodeBlock component already falls back to "plain" if the language is not available, possibly no changes needed there

Closing this request based on received feedback; will not be implemented as swizzling the code block is a proper alternative.
