* Change Python version guard: PYTHON < 3.7 IS UNSUPPORTED.
* Replace or remove Python 3.6 jobs.
* Move appveyor to Python 3.8
* Change `[tool.pylint]` `master.py-version` from `3.6` to `3.8`
* Change `[tool.pylint]` `master.py-version` to `3.7`
* Remove `centos:7` job; Change almalinux:8 job to use Python 3.8
* Try 🐍 3.8 • ubuntu-20.04 • x64 without `-DCMAKE_CXX_FLAGS="-D_=1"`
* Update setup.cfg as suggested by @henryiii
* Try running `cmake --build . --target cpptest` on all platforms (`standard` job).
* Disable deadsnakes jobs entirely.
* Apply PR #5179: Add Python 3.10, 3.11, 3.12 to win32 job matrix.
* Add back `-DCMAKE_CXX_FLAGS="-D_=1"` but do not install boost in that case.
* PY_VERSION_HEX < 3.7 cleanup pass: include/pybind11
* WITH_THREAD cleanup pass: include/pybind11
* Undo incorrect change.
* Revert "Disable deadsnakes jobs entirely."
This reverts commit bbcd0087b2.
* WITH_THREAD cleanup pass: tests/
* Change Python version guard in pybind11/__init__.py: pybind11 does not support Python < 3.7.
* Misc cleanup pass
* chore: use future imports

* Update tests/test_numpy_array.py
* Update test_numpy_array.py
