In order to remove warnings about /apidoc/*.rst files being included
multiple times in toc when building full swh documentation, prefer to
include module indices only when building standalone package documentation.

- pre-commit from 4.1.0 to 4.3.0,
- codespell from 2.2.1 to 2.2.2,
- black from 22.3.0 to 22.10.0 and
- flake8 from 4.0.1 to 5.0.4. Also freeze flake8 dependencies.

Also change flake8's repo config to github (the gitlab mirror
being outdated).

For now this is a naive implementation, which does never rechecks.

For now, this does not use this information to deduplicate work.

It will be used by the storage_checker to 'remember' what ranges
it already checked recently across runs (and crashes), and to
monitor progress.

It will probably be useful to know what part of the check
takes the most time.

This will allow adding more tags easily in future commits

instead of (soon-to-be-deprecated) swh-core's postgresql_fact one.

This alleviates current locking issues where nothing gets written in production.

We migrated away from "local" a while back.

The case where the datastore already exists was masked by @functools.lru_cache,
which persists for the lifetime of a test, causing the function not to be
actually called twice.

black is considered stable since release 22.1.0 and the version
we are currently using is quite outdated and not compatible with
click 8.1.0, so it is time to bump it to its latest stable release.

Please note that E501 pycodestyle warning related to line length
is replaced by B950 one from flake8-bugbear as recommended by black.

This is heavily inspired by https://archive.softwareheritage.org/swh:1:cnt:c6dda7698c6aecf71f744e4e4c01bc3e115db880;origin=https://forge.softwareheritage.org/source/snippets.git;visit=swh:1:snp:c2e3170b9927f3d356e120546b00f5a9d25a224c;anchor=swh:1:rev:fa9e387ba5e3470b93a5c5a8773ed598ef03d211;path=/vlorentz/analyze_consistency_failures.py
but reorganized to the database instead of ad-hoc text and pickle files.

Currently, this only implements recovering from Git origins.

pytest-postgresql 3.1.3 and pytest-redis 2.4.0 added support for
pytest >= 7 so we can now drop the pytest pinning.

as well as the run() method.

For consistency with a future module called fixer.py

Due to test modules being copied in subdirectories of the
build directory by setuptools, it makes pytest fail by raising
ImportPathMismatchError exceptions when invoked from root
directory of the module.

So ignore the build folder to discover tests.
