Bumps actions/setup-python from 2 to 4.

Release notes

Sourced from actions/setup-python's releases.

v4.0.0

What's Changed

• Support for python-version-file input: #336

Example of usage:

- uses: actions/setup-python@v4
  with:
    python-version-file: '.python-version' # Read python version from a file
- run: python my_script.py

There is no default python version for this setup-python major version, the action requires to specify either python-version input or python-version-file input. If the python-version input is not specified the action will try to read required version from file from python-version-file input.

• Use pypyX.Y for PyPy python-version input: #349

Example of usage:

- uses: actions/setup-python@v4
  with:
    python-version: 'pypy3.9' # pypy-X.Y kept for backward compatibility
- run: python my_script.py

• RUNNER_TOOL_CACHE environment variable is equal AGENT_TOOLSDIRECTORY: #338

• Bugfix: create missing pypyX.Y symlinks: #347

• PKG_CONFIG_PATH environment variable: #400
