ci: update workflows for forked repo

Most of the CI workflows ported over from the fork of
informalsystems/hermes are not passing. Let's ditch those and re-add a
narrow set of rust checks, so that Penumbra Labs developers can trust CI
when making changes.

Also adds a modified container-build workflow, so that we can run a
container image of Hermes in CI deployments.
