   Rather than continue to close PRs/“Send these upstream” i.e: #33638, #33148, #22664, #13781; just fix the typos.

   Includes https://github.com/bitcoin-core/leveldb-subtree/pull/57.

   Verified that subtree matches commit bitcoin-core/leveldb-subtree@cad64b151dabe9ffe9771a54d7c9dbfb3355cefb, and the changes are trivial.
