Merge branch 'ps/commit-graph-less-paranoid' into maint-2.43

Earlier we stopped relying on commit-graph that (still) records information about commits that are lost from the object store, which has negative performance implications. The default has been flipped to disable this pessimization. * ps/commit-graph-less-paranoid: commit-graph: disable GIT_COMMIT_GRAPH_PARANOIA by default
