ci: patch run with no tests

[Borda]

What does this PR do?

Open #2345 revealed we had false positive failing cases when there were only docs changes

torchmetrics/.github/assistant.py

Lines 135 to 136 in dc115fe

	logging.debug("Only docs was changed so not reason for deep testing...")
	return ""

The assistant for docs or other no-code changes returns an empty string, but that is interpreted by running all, including integrations which has missing requirements
