ENG-2232 ParameterChangeProposal type possibly not working

Steps to reproduce

The community recently tried to raise the minimum deposit for governance proposals in order to prevent spam with the legacy - "/cosmos.params.v1beta1.ParameterChangeProposal" but it seems to not have worked even thought it passed

Querying mainnet you can see it hasn't changed

Expected Behaviour

• Deprecate v1beta1 for the proposal.
• Update documentation to reflect this change.

Looks good! Thanks @GAtom22 🙏 Maybe it could be easier to just create one page outlining the proposal drafting process as a suggestion.
