Subject: [PATCH] chore: fix x/mint param sims (#12461)

`RandomizedParams` generates random parameter changes during simulations, however, it does so through `ParamChangeProposal` which is now legacy.

Once all modules are migrated we will remove `RandomizedParams` entirely from the simulation interface.

For now, we just return an empty slice.
