Update version in workflow actions and enable 3.13 (#97)

* Update actions versions
* Add concurrency

Prevent from running the workflow more than once for the same
pull request or for the same commit hash

* Use pre-releases from action/setup-python

Drop complexity of the workflow and tox config by not using
deadsnakes GitHub Action. Instead, use setup-python action's
pre-release versions.

* Add 3.13 classifier to pyproject.toml
