QtAA: Drop developer-builds from CI

We used to build the documentation with these configurations but they
changed to developer-builds and the documentation was moved to a
separate configurations (documentation-warnings, offline-documentation).

We added those configurations but ignored the developer-builds, and at
the moment they are not doing anything expect wasting resources when
acquiring VMs, so let's get rid of them.
