feat: editor katext extension

[xinkeng0]

The katex extension for richtext-editor is coming. 🎇 Consistent editing experience with the richtext-editor.

There are currently some known minor issues.

• The bubble menu should not appear when clicking on a formula.
• The style of the formula component is not attractive enough.
• Internationalization support.
• Block-katex paste support.(Now always taken over by inline-paste-Regex.)

Anyway, it's time to experience the formula plugin!
