Update build action to leverage generate artifact

[relent0r]

Description of changes
This PR updates the build action to leverage the generate artifact. It will trigger the generate action then use the artifact output in its processing. Then upload another artifact of its own output for deployment.

Testing method
Manual action requires to be taken on the default branch. Have tested with a push trigger to validate that the artifact and contents were created.

During testing you can see the actions being validated in my fork https://github.com/relent0r/spooky-db

closes #125

Only caveat is that I'm not 100% sure that it is replacing the existing files on artifact dl.

Given:

• https://github.com/FAForever/spooky-db/actions/runs/9320695240/job/25658044578

Reviewing the output of ls -R before and after downloading the artifacts it should be fine now. The output of the artifact is flat, the app/data path is lost. We need to manually put them there again.

About running this particular workflow locally: it appears that it stalls on the powershell script. No matter what I do the CPU usage is near 0 and it appears to be doing nothing. Not even the initial printing (for the parameters) is in the console.
