🧪 Run gh release w/o Git in CI/CD

It is possible to use `gh release create --repo=` [[1]] so that GH CLI
does not need to infer the repository information from the Git
repository.

GH CLI supports passing such options via environment values [[2]],
which is what this patch makes use of.

It's a follow-up for pytest-dev#13891.
