don't install recommends when installing packages

update our actions

add dependabot config to update our actions automatically

Only run package bumping on theforeman

Otherwise forks also run the same, which is wasting a lot of resources
and sending failure messages to Discourse.

send one notification if bumping failed

also correct the link to actually render properly

based on the example in https://docs.github.com/en/actions/learn-github-actions/contexts#example-usage-of-the-needs-context

set non-empty sender address

discourse doesn't like mail w/o from address
