Change in-editor documentation style to match online docs.

[bruvzg]

Some minor in-editor documentation style changes:

• Adds bullet to the property, constant, enum and method descriptions.
  
• Rearranges some newlines.
  
• Fixes inheritance and enum line font size mismatch.

Yay for consistency! But what's up with the enum keyword on the second one? Is it that small on purpose?

Is it that small on purpose?

No idea, I have not changed it, it was always small for me. If it's intended to be small, it's probably HiDPI scaling issue (and wrong inheritance size might be the same issue).

Probably is a HiDPI issue, looks fine to me:

Yep, it's using default font instead of docs, updated PR.

Looks good to me 🙂

For extra consistency, the — (em dash) character could be used to separate enum/constant values and their descriptions. If it's too long, then – (en dash) can be used instead.

Update: Added cell border/background color support to the RichTextLabel (disable by default), and some table borders to the documentation (overview and properties, as the separate commit).

Changed it to en dash.

I like the idea, but from your screenshots on my display it's barely noticeable.
Also, some cells clearly need their inner padding adjusted. Like the ones with the type.

Added some padding (and cell padding support to the RichTextLabel), and changed colors to the editor theme default background variants.

Move initialization to the declaration.

Edit: Fixed typo.

While the added RTL features look nice, I think they might warrant a dedicated PR as it's a core change, and it will conflict with #39248.
The rest of the doc style changes should be mergeable without second thought already.

Done, RTL related changes are in #39587
