feat(richtext-lexical): client-side block markdown shortcuts, code block

[AlessioGr]

This PR:

• adds support for client-side markdown shortcuts for blocks with the admin.jsx property. This was previously only supported server-side. The code mimics the server-side implementation, as this could be used for full markdown imports on the client-side, rather than just simple markdown shortcuts
• exports a pre-made CodeBlock that can be used within the BlocksFeature. Video Example:
