Replace https://gitlab.com/pycqa/flake8 with https://github.com/pycqa/flake8

[JPBergsma]

I noticed that in .pre-commit-config.yaml
we use https://gitlab.com/pycqa/flake8
but in the output under https://github.com/Materials-Consortia/optimade-python-tools/actions/runs/3470260414/jobs/5798242394
subsection run precommit we somehow use: https://github.com/pycqa/flake8
While in testrun https://github.com/Materials-Consortia/optimade-python-tools/actions/runs/3472198532/jobs/5803041964
https://gitlab.com/pycqa/flake8 is used which does not work.
I therefore suggest we change https://gitlab.com/pycqa/flake8 to https://github.com/pycqa/flake8 in .pre-commit-config.yaml

I also ran into this yesterday when they finished the flake8 migration, its already fixed in #1373 (just finalizing it now)

Do you by any chance also fix a " ModuleNotFoundError: No module named 'yaml'" error in that PR?

[ml-evs]

I haven't run into that one... from a fresh install I have the following:

$ pip freeze | grep yaml
pyyaml_env_tag==0.1
ruamel.yaml==0.17.21
ruamel.yaml.clib==0.2.7

[JPBergsma]

I can solve the yaml issue by adding pyyaml to setup.py under install requires.
see PR#1304

I'll close this issue as it's topic "Replace https://gitlab.com/pycqa/flake8 with https://github.com/pycqa/flake8" has been resolved.
we can discuss the " ModuleNotFoundError: No module named 'yaml'" error elsewhere like in PR#1304
