Feat: markdown editor commands

[maxb2]

This adds more buttons in the markdown note editor.
Closes #440

TODO:

• Refactor new functions. There's a lot of repeated code right now.
• Roll Macro template. Very simple. Selected text becomes the chat message.
• Lists
  • Unordered
  • Ordered
    • Increment numbers in raw markdown? Rendered html doesn't care what the numbers are. Maybe in the future.
  • Checkbox
    • Render check boxes.
    • Make check boxes togglable when rendered Would require editing note. Maybe in the future.
  • Convert between kinds of lists.
• Text tools
  • Cycle header levels
  • Paragraph It would just add a newline, so I don't see the point...
  • Strikethrough
  • Code
  • Quote. Could use a better icon.
  • Table

The quote looks a bit weird, I think we can style it better.

Also, the checkbox styling can be improved, to look more similar to github:

Toggling it it would be a great feature!

I changed it to a chakra Checkbox. I liked it better and it should give us more consistent styling.

I agree.
I updated the quote style to be the same as ScrollableList.ListItemButton.
I have no strong feelings for any of the styling, so feel free to make any suggestions/changes.
Here is a sample of what everything looks like:

I'd love to have them be togglable and update the markdown note accordingly (Github issues does this), but I'm not sure how to implement it.

@n1ru4l this is ready for review. It can be merged as-is unless you really want to be able to convert between list types (requires some more regexing). Added converting between list types.
