Add pygments to pyproject.toml

[adamgreig]

Thanks for strictdoc, I'm trying it out and really like it so far.

I noticed pygments is a dependency but it's not listed in pyproject.toml, which means a pip installation fails unless you also install pygments separately. It's in the poetry.lock and reqirements.txt, so I guess the CI didn't notice:

/tmp$ python3 -m venv venv
/tmp$ source venv/bin/activate

If it's helpful, this PR updates pyproject.toml and the corresponding lock file and bumps the version in requirements.txt to match. No problem if there's some other way you prefer to update them though.
