✨ Add standard `nox task(s)` for creating a release

[Nicoretti]

Summary

To streamline the process of creating and publishing releases, the Python Toolbox shall introduce standard tasks for these actions. These tasks should be readily adaptable for both project-level utilization and integration into workflows.

Details

The tasks should be nox based and work both locally and within continuous integration setups. Each task should focus on a specific aspect of the release process rather than attempting to encompass all release-related actions in a single task. E.g.:

• check release version
• build project/wheel
• create tag
• push tag to origin
• publish to gh
• publish to pypi
• output release information

Further information also can be found in the currently unimplemented nox tasks stub exasol.toolbox.nox.tasks:release.
