This PR adds the post-mortem for a bug that was introduced in the v8.1.0 release on Mainnet.
Brief Overview
There is a bug in the Evmos v8.1.0 upgrade. The upgrade registers an outdated upgrade name, so that the feesplit module is added without running the store upgrade. Without this store upgrade, new modules that are added to the chain don't work.
Impact: Feesplit module queries and transactions are unsuccessful. Other modules are unaffected.
