chore(deps): upgrade async-nats and enable FIPS

[pront]

Summary

Bump the async-nats dependency to the latest version and turn on the FIPS backend.

Bumping the version is trivial but this PR also updates all environments/runners to include the dependencies necessary to build the FIPS backend. For example, we have to install Go (mega-sad) in our CI because it is a build dependency.
