Make AsyncPersistedState.resetVotingConfiguration fast (#88050)

Using the builder just to update that one field in the metadata means
running through the name collision checks on the metadata which are very
expensive. In the many-shards benchmark run it takes ~2% of total CPU
time just for this operation.
Even though this is running async on a thread off the critical path I think
it's worthwhile fixing this to free up some CPU for other tasks.
