[SylvestreG]

This PR bumps dependencies to last cosmwasm dependencies.

looks great! just a couple little nits, then i'd be happy to land this.

so it looks like the last failure here is that const-old which is a dependency of cosmwasm-crypto is on the 2021 edition of rust. as we can't get around that dependency, we should probably upgrade our github action here to use nightly.

@SylvestreG would you mind updating that? can probably literally copy-paste the DAO DAO workflow from here.

Sure, just tried with 1.63.0 that should be enough :) If it not works I will bump to nightly :)
