I am able to confirm that the test package, 1:2.34.1-1ubuntu1.9+sf363767v20230707b1, fixes the issue.
I installed the test package, confirmed it was fixed, downgraded to git 1:2.34.1-1ubuntu1.9 git-man=1:2.34.1-1ubuntu1.9 (the normal jammy package), confirmed it was broken, upgraded again to the test package, and re-confirmed it was fixed.
I also reviewed the debdiff. Everything appears in order to me.
