fix: add cosmos.msg.v1.service to message services

[faddat]

What is the purpose of the change

This pull request resolves an issue I encountered with using Osmosis modules in a third party chain:

    service osmosis.poolmanager.v1beta1.Msg does not have cosmos.msg.v1.service proto annotation
    service osmosis.tokenfactory.v1beta1.Msg does not have cosmos.msg.v1.service proto annotation
    service osmosis.poolmanager.v1beta1.Msg does not have cosmos.msg.v1.service proto annotation
    service osmosis.tokenfactory.v1beta1.Msg does not have cosmos.msg.v1.service proto annotation

I think that the difference between osmosis and the other chain is the use of appv2, so I checked IBC and cosmwasm, and found the annotation there.
