chore: godoc pointing to wrong version (osmosis-labs#2559)

## What is the purpose of the change

Our godoc and go report card were both pointing to the latest v1 branch, when in reality it should be pointing to the v11 package which then pulls the latest version from that.

Lastly, this PR gets rid of a broken / nonexistent link.
