Custom Unified.js Plugins (Admonitions + Type Links)

[YetAnotherClown]

This PR introduces one new Remark plugin and a new Remark-Rehype Handler, both of which resolve issues or outdated features resulting from the upgrade to Docusaurus v3 and the major bump of dependencies.

Remark-Rehype Handlers for Admonitions

docusaurus-plugin-moonwave now uses a custom remark plugin that uses remark-directive to turn commonmark directives in markdown into Docusaurus-style admonitions.

These new handlers adds support for:

• Inline Directives :note[Some description]
• Leaf Directives ::note[Some description]
• Markdown in admonition heading
• Nested admonitions

This is ultimately a replacement for remark-admonitions, which is outdated and not used in Docusaurus v3 anymore, Docusaurus now has a built-in admonition plugin.

By replacing it, we get access to new features brought with remark-directive, and a custom handlers to allow us to replace Docusaurus admonitions with our own by replacing markdown directives directly with our own admonition components in the future.

Extended Link References Plugin

In the updated version of Unified, they patched Link References with no definitions, e.g. [label]. While they consider this parsing to be a bug, Moonwave of course used it for type links. This plugin includes a Micromark syntax extension and an extension for mdast-util-from-markdown which re-adds support for this syntax.

Other

• Added back support for GitHub Flavored Markdown which was removed in remark-parse version bump.
