Deduplicate and summarize workflow file.

Said up-to-date, not on a branch, had to `git pull origin master`.

- dep
- Eluna
- realmd
- Extractor_projects

Strange each was in a detached HEAD state with a lot of changes / absent items.
Cleaned those / discarded all changes, then pulled for each directly because of that problem not allowing easy looping from git.

Already current:
- SD3
- win

For Eluna since it caused a `Hook.h` error.

to be consistent with master branch.

Add `source` to package script invocation.
Bring back commands for Windows build without script execution capability.
