Python 3.11: pygments re.compile error

[kbandla]

With Python3.11, pygments fails with the following message:

>>> from pygments import highlight

Python versions 3.7 and later showed a DeprecationWarning:

Flags not at the start of the expression '<(.+?)(\\s.*?)?>.*?</' (truncated)re.compile(r'<(.+?)(\s.*?)?>.*?</.+?>(?uism)')

Yes, this is a known issue. I'll upgrade the pygments version soon.

Should be fixed with 9a852b5c04c318f1844821d4a17026204c395155. Feel free to reopen if you have any issue.
