Fix yaml comment indent (#33882)

Closes #33761

The problem was that in the indentation regex we were treating lines
that had `:` in them as requiring an indent on the next line, even if
that `:` was inside a comment.

Release Notes:

- Fixed YAML indentation for lines containing comments with `:` in them
