Fixed RichTextPropertyPane text-indent bug.

Text indent buttons were copy-pasta of subscript and superscript buttons. Clicking on the text-indent buttons would call subscript or superscript instead.

Oops, looks like I included some unnecessary formatting, sorry about that.
How do I avoid that?

Hi @SharePickle,

Thanks for the fix! It will be included in next version, but you can already test it in beta version.

Some components in this repo were created when VS Code had default indent of 4 spaces. Now the default is 2 spaces. Most probably you applied formatting to the whole file that led to changed indents.

Anyways, I merged the PR :)
