CI Jobs have logic to find the merge base, and compare changes against it to determine which packages have changed in the PR
Previously, it used a fetch-depth of 2, to avoid downloading the whole monorepo history. This could cause issues finding the base, which would trigger a full test run (see #18166)
This PR does a full fetch (fetch-depth: 0), but filters out blobs, so the clone and comparison is still fast
