Fixed unknown symbol drawn instead of tabs in breakpoints/bookmarks lists

Tab characters were not rendered properly in the breakpoints and
bookmarks lists of the script editor if the bookmarked line was a
comment, resulting in unknown ASCII symbols “�”.

Fixes #34046.

Also changed formatting a bit to enclose the code in backticks (like in
Markdown) instead of quotes.
