Bump evmos version to v9

[facs95]

Description

This change was originally done on 786 but that involved the upgrade to SDK 46. Which makes it complicated for releases.

I decided to do this in an independent PR given the amount of files it involves for ease of review. Once this is merged I can cherry pick the two changes needed for this release. 🙏
