Subject: [PATCH] ci: build containers on merge or tag (#4767)

## Describe your changes
We'd previously been triggering container builds on every merge to main,
via the testnet deploy workflows, which were removed in #4678. Let's add
triggers to build containers regularly, even though we're not deploying
them automatically. Also cleans up unused builds like for galileo and
grafana.
