##
## This workflow handles testing of pull requests and pushes.
## It also publishes some packages to any new Erlang/OTP release
##
## To speed this up it would be nice if one could share docker
## images inbetween different jobs, but at the moment this is
## not possible so we need to rebuild all of Erlang/OTP multiple
## times.
##
## Now that we have migrated to ghcr.io we use the
## built-in caching mechanisms of docker/build-push-action@v2.
## However as things are now we use docker directly to make things
## work due to historical reasons.
