We only need commit hashes, not the trees or the content. Let's use partial fetch:
git fetch --deepen=100 --filter=tree:0Most providers support this. If that's not the case, fallback with git fetch --deepen=100 --filter=blob:none (fetch the trees but not the content), and, finally, with git fetch --deepen=100 (full fetch).
In 99% of cases, that will reduce the amount of downloaded data and fetch execution time massively:

CI usually has shallow fetch depth clone of a repo, lacking enough first-parent history for git lineage.
This PR deepens ancestor collection.
