Subject: [PATCH] haskellPackages.pandoc-crossref: revert patch requiring
 pandoc>=3.8

- The linked issue has been resolved, but the updated bounds are only
  available on master.
- 0.3.21 contains a patch for an interface deprecation in pandoc 3.8
  which we need to revert in order to build with pandoc 3.7.

(cherry picked from commit f2b98de78a3a2967cf011f10beacef2088daf0f2)
