@azeey Are we deploying the acropolis or blueprint docs still?

I assume this is asking about the workflow changed in this PR. We're currently only building the non-EOL releases, so no, we're not deploying acropolis and blueprint. However, the last built documentation is still accessible. For example, the gz-sim API docs from blueprint are at https://gazebosim.org/api/sim/2/

LGTM!
However, this workflow will likely become obsolete when #441 is finished and merged.
