fix: stop pruning the cached action ref on refresh (#1312)

The action cache refresh fetched with `--prune` and the unqualified refspec `+<ref>:refs/runner/<hash>`. Git cannot map that ref back to a remote ref, so it deleted it on every other refresh. The first job after a branch or tag moved then failed with `cannot lock ref`, and a moved tag in a full clone could silently run its old commit. `--no-prune` fixes this and also overrides an inherited `fetch.prune`.
