Stash save lacks gh and jq dependencies in container

.github/​workflows/​velox_backend_cache.yml:36

This job now runs apache/infrastructure-actions/stash/save inside the AlmaLinux container (at lines 56-61), but the image only provides the base Python and does not include the gh/jq dependencies that stash actions require. The cache job will therefore fail while saving to Apache Stash; install the stash dependencies in the container before the actions, or keep this action on the host runner.

This issue also appears on line 134 of the same file.
