Upgrade CosmWasm to v2

[Buckram123]

Osmosis just upgraded their chain to support CosmWasm v2 as well as their package osmosis-std. Upgrading mars is a requirement for any project that use mars to upgrade CosmWasm and Osmosis packages

Bumping this issue. Our money-market adapter feels left out :/

Hey!

Quick update:

We have it on the todo list but the problem is that some of the dependencies we use are not yet migrated to v2. We are monitoring the situation and will update as soon as possible.
