`main` branch missing changes from previous `master` branch

[damiannolan]

It appears the main branch (default) on the repository is missing some changes from the previous default (master) branch.

Most notably what came to my attention was that the cosmwasm contract apis for the 08-wasm go module are not in sync / update to date.

For example the InstantiateMsg is completely empty on main.

#[cw_serde]
pub struct InstantiateMsg {}

Whereas on the master branch, it is populated with fields.
