feature: WYSIWYG markdown for notes. Fixes #701 (#715)

* #701 Improve note support : WYSIWYG markdown

First implementation with a wysiwyg markdown editor.
Update:
- Add Lexical markdown editor
- consistent rendering between card and preview
- removed edit modal, replaced by preview with save action
- simple markdown shortcut: underline, bold, italic etc...

* #701 Improve note support : WYSIWYG markdown

improved performance to not rerender all note card when one is updated

* Use markdown shortcuts

* Remove the alignment actions

* Drop history buttons

* Fix code and highlighting buttons

* Remove the unneeded update markdown plugin

* Remove underline support as it's not markdown native

* - added ListPlugin because if absent, there's a bug where you can't escape a list with enter + enter
    - added codeblock plugin
    - added prose dark:prose-invert prose-p:m-0 like you said (there's room for improvement I think, don't took the time too deep dive in) and removed theme
    - Added a switch to show raw markdown
    - Added back the react markdown for card (SSR)

* delete theme.ts

* add theme back for code element to be more like prism theme from markdown-readonly

* move the new editor back to the edit menu

* move the bookmark markdown component into dashboard/bookmark

* move the tooltip into its own component

* move save button to toolbar

* Better raw markdown
