Update automated tests, pass as-is

[Avasam]

Work towards #296

Counterpart to #302 but this only touches configurations and infra. No stub change here except for stubs/scipy-stubs/optimize/cython_optimize/__init__.pyi (which is purely a mypy workaround otherwise it wouldn't even run due to same-name modules). So you can decide which you want first. There will be slight conflicts but I'll resolve them.

• Add mypy, isort and black tests to GitHub actions
• Move pyright configs to be automatically picked up by Editor, CLI and CI
• Move typeCheckingMode setting from IDE only to pyright configs
• Move warn-partial setting from GitHub actions to pyright configs
• Remove redundant default mypy settings
• Turn on show_column_numbers in mypy
• Bump minimum supported version to 3.8
• Ignore existing errors (preferably as warnings) and mark them as TODO
• Exclude/skip files where the error cannot be globally ignored, and mark them as TODO
• Remove empty tests/__init__.py
• Add stubs/scipy-stubs/optimize/cython_optimize/__init__.pyi to get mypy to run
• Added all parent libraries needed to validate typing in tests/requirements.txt
• Use pyright-python's PYRIGHT_PYTHON_PYLANCE_VERSION to ensure better sync with Pylance
• Converge tests/run_tests.sh and tests/run_tests.cmd into a Python script, simplified the commands, and update to run all the tests
• Added tests/run_formatters.py to run all code fixers and formatters

Updated with latest review comments! Btw feel free to squash commit once this is accepted. I avoid rebases/force-pushes on GitHub to make it easier on the reviewer to see latest changes.

Unless you have any other comment, it's good to be squash-merged on my side if it passes the CI. #301 (comment) and #301 (comment) are more follow-ups than something to be done here.

The conflict is caused by:
The user requested typing_extensions==4.2.0
mypy 1.11.2 depends on typing-extensions>=4.6.0
The user requested typing_extensions==4.2.0
mypy 1.11.1 depends on typing-extensions>=4.6.0
The user requested typing_extensions==4.2.0
mypy 1.11.0 depends on typing-extensions>=4.6.0

I unpinned typing_extensions to just follow what mypy uses

When installing the requirements on a fresh install of Python 3.10, I got the following warning:
DEPRECATION: docopt is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559

That led me to docopt/docopt#502 (comment): even docopt organization members are recommending to switch over to docopt-ng due to docopt being unmaintained in the past 6 years (last release 10 years ago)
