no concrete type registered for type URL /juno.v1.clock.UpdateParamProposal

When using the juno command: oraid tx clock add-contract, we received the following error:

After debugging for a day, the closest I have got to understand this bug is that:

• Cosmos SDK 0.50x has changed the way it handles gov proposals.
• Instead of whitelisting the gov proposal content (like /juno.v1.clock.UpdateParamProposal), it recursively validates the entire MsgSubmitProposal message, consider any sub-messages within it also to be a Cosmos message as well.
• Because /juno.v1.clock.UpdateParamProposal is not a message -> hence the error

My attempt to fix the bug by registering /juno.v1.clock.UpdateParamProposal didn't work, even though it bypassed the above error:

registry.RegisterInterface("juno.clock.v1.UpdateParamsProposal", (*sdk.Msg)(nil), &UpdateParamsProposal{})

This is because there are additional checks for the message such as no cosmos.msg.v1.signer option found for the message.

This is odd, because it should not be intended to be a message.

I then switched to a new direction, by using the new official way of submitting gov proposals: https://docs.cosmos.network/main/build/modules/gov#messages

I added a new msgServer message, called MsgUpdateParams and registered it as a message. I also added its basic Msg implementations.

Fortunately, it worked.
