fix: fixed the cosmwasm msg types

[dadamu]

The typescript file of messages using new macro cw_serde then generated by codegen are no longer fix Record<string, unknown>. The msg types should be JsonObject, instead.

The reason is as follows:

1. schema json changed to have value "additionalProperties": false by this change in cw_nfts
2. codegen ts structure loses [k: string]: unknown, it can be found at cw721-base-instantiate-with-cw-serde and cw721-poap-instantiate-without-cw-serde
3. without [k: string]: unknown field, message is no longer to match Record<string, unknown>

Interesting. I came across a this issue recently as well when writing a interface MyManualMessageTypeDefinition { ... }. Wanted to change this to any. But maybe this fix is better.

Nevermind, type JsonObject = any

I picked up this work and extended it a bit in #1284. Thanks a lot!
