Use annotations instead of // Since XX comment

[julienrbrt]

Rewrite all // Since comments in our proto files as cosmos_proto.method_added_in, cosmos_proto.field_added_in, etc..

Example:

• cosmos-sdk/x/bank/proto/cosmos/bank/v1beta1/tx.proto

  Lines 35 to 40 in 0cf0c28

  	// on any number of Denoms. Only the entries to add or update should be
  	// included. Entries that already exist in the store, but that aren't
  	// included in this message, will be left unchanged.
  	//
  	// Since: cosmos-sdk 0.47
  	rpc SetSendEnabled(MsgSetSendEnabled) returns (MsgSetSendEnabledResponse);

• cosmos-sdk/x/bank/proto/cosmos/bank/v1beta1/tx.proto

  Lines 144 to 147 in 0cf0c28

  	// MsgBurnResponse defines the Msg/Burn response type.
  	//
  	// Since: cosmos-sdk 0.51
  	message MsgBurnResponse {}

• cosmos-sdk/x/gov/proto/cosmos/gov/v1/query.proto

  Lines 170 to 173 in 0cf0c28

  	// params defines all the parameters of x/gov module.
  	//
  	// Since: cosmos-sdk 0.47
  	Params params = 4;

Then re-generate all protos (using make proto-gen)

Troubleshot `make proto-gen`

You may find issues when doing a buf mod update in each folder until #19503 is completed. Instead, simply update each relevant buf.lock as follows:

    owner: cosmos
    repository: cosmos-proto
    - commit: 1935555c206d4afb9e94615dfd0fad31
    - digest: shake256:c74d91a3ac7ae07d579e90eee33abf9b29664047ac8816500cf22c081fec0d72d62c89ce0bebafc1f6fec7aa5315be72606717740ca95007248425102c365377

Follow-up of #20083 and cosmos/cosmos-proto#133

Hi @julienrbrt , we just push a pr for this issue, please take a look, thank you

Answering #20167 (comment) here.
I don't think it is useful to denote this, imho. Enums need to be used somewhere, and they will be mostly denoted in message added in or field added in.

Feel free to just remove that comment.
