add requirements files to ingest cache hash key (#3641)
This PR adds the requirement files for base and extras for the ingest
cache's hash key.
- The current workflow uses only the ingest requirements to generate
hash key for the gitaction cache
- Sometimes only base or extra requirements (like extra-pdf.txt) updated
but not any ingest requirements -> this would mean the ingest test would
fetch a cache with outdated non-ingest dependencies
- When we generate new ingest cache we actually do check first base and
extra requirements and generate a base env before layer on top the
ingest dependencies.
- This PR allows the ingest step to recognize changes to non-ingest
dependency changes and trigger new cache generation when either ingest
or base/extra requirement files changes.
This PR also bumps the setup python action version in cache actions; it
also adds installation of `virtualenv` for the ingest cache action to
avoid errors like
