html: Exclude all brackets from bracket colorization (#46808)

Closes #45755

Rainbow brackets in HTML files do not really make sense - a tag is
always enclosed in angled brackets. With our current approach, that
means that we will highlight all brackets in HTML files with the same
color, because well, these angled brackets do not quite behave like in
other languages.

Hence, let themes color this again and just exluce HTML angled brackets
from rainbow bracket colorization, as it is no real rainbow bracket
colorization anyway.
