pygments >= 2.12

[Mads Kiilerich]

Hi Pawel

Thanks. I have applied the fix.

Note that the setup.py install procedure makes it clear that Kallithea 
currently only supports pygments < 2.8 . You might encounter other 
problems by using unsupported versions. Other libraries might cause even 
more serious problems.

It would however be nice to bump the officially supported pygments 
version. And to keep the changes simple, perhaps drop support 
for pygments < 2.8 ... at least for running the tests. Updating pygments 
will unblock the upgrade of other libraries ... which might expose other 
problems, which makes it more risky and non-trivial.

Regards,
Mads
