fix: wait for medium e2e to finish and pass

[cdoern]

the medium e2e job should:

1. be blocking
2. use pull_request_target properly to gate access to secrets from untested code

⚠️ The sha of the head commit of this PR conflicts with #606. Mergify cannot evaluate rules on this PR. ⚠️

[booxter]

This seems wrong since the change doesn't get rid of secrets read in e2e step. Unless we can fetch models and such without tokens, we cannot have the job as pull_request_target.

I am still working on this, comparing it to the one in instructlab/instructlab. In the meantime we can consider disabling this workflow on PRs if there is one we need to merge.
