[hugovk]

Fixes a deprecation warning at https://github.com/jazzband/geojson/actions/runs/4012584880

> PyPA publish to PyPI GHA: UNSUPPORTED GITHUB ACTION VERSION <<#L1 You are using "pypa/gh-action-pypi-publish@master". The "master" branch of this project has been sunset and will not receive any updates, not even security bug fixes. Please, make sure to use a supported version. If you want to pin to v1 major version, use "pypa/gh-action-pypi-publish@release/v1". If you feel adventurous, you may opt to use use "pypa/gh-action-pypi-publish@unstable/v1" instead. A more general recommendation is to pin to exact tags or commit shas.

Also bump other GitHub Actions, should fix some or all of the other warnings:

Node.js 12 actions are deprecated. Please update the following actions to use Node.js 16: actions/checkout@v2, actions/setup-python@v2, actions/cache@v2. For more information see: https://github.blog/changelog/2022-09-22-github-actions-all-actions-will-begin-running-on-node16-instead-of-node12/.

The set-output command is deprecated and will be disabled soon. Please upgrade to using Environment Files. For more information see: https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/

The save-state command is deprecated and will be disabled soon. Please upgrade to using Environment Files. For more information see: https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/

And simplify config:

• Change guard to github.repository_owner == 'jazzband', makes it easier to compare files across Jazzband repos, makes easier to maintain
• Use actions/setup-python's own builtin pip caching
