setup.gha.py

'''
minimal (but likely growing) subset of `gardener-cicd-libs` package for usage w/ GitHubActions.

This package takes special care to avoid dependencies specific towards Concourse-Pipeline-Template
or related infrastructure (e.g. `concourse`, `ccc`, `model` packages), and also omits dependencies
against some "heavy" packages, such as hyperscaler-SDKs, which are referenced by `gardener-cicd-libs`
for historical reasons.

Caveat: as this package has overlaps w/ `gardener-cicd-libs`, it is not adviseable to create mixed
installations (containing both `gardener-gha-libs` and `gardener-cicd-libs`).
