helpers: very partial support for pygments >= 2.12

setup.py makes it clear that Kallithea only supports "Pygments >= 2.2.0, < 2.8".
Later versions are known to cause minor breakage to tests, and it hasn't been
validated that they don't expose other problems.

Pawel (aka momat) reported a problem with pygments >= 2.12 when subclassing
HtmlFormatter. The wrap outfile parameter has been dropped, and he suggested
this workaround.

The workaround seems safe and backwards compatible and nice to have, but we
still don't recommend or support using Pygments >= 2.8 .
