Proto changes look good. Please revert everything else 👍

[alexanderbez]

Undo 👍

[aaronc]

I did that because otherwise I had no idea vendor was messing up protoc. I can revert, but if anyone else runs go mod vendor they'll have problems.

[alexanderbez]

Undo. Instead, update the protoc-gen-gocosmos target to install a specific version:

protoc-gen-gocosmos:
  @(cd /tmp && github.com/regen-network/cosmos-proto/protoc-gen-gocosmos@VERSION)

We cd into tmp to not pollute go.mod -- hacky, but idk another way.
