Add hatch_build.py to k8s test venv cache calculation (#39473)

With dynamic project depdencies, the requirements for airlfow are
calculated dymamically from hatch_build.py, however cache invalidation
key for k8s tests only included pyproject.toml so when colorlog has
been bumped in @39453, main build continued to use cache from old
colorlog.

This PR adds also hatch_build.py to cache id calculation
