Files created by the build are owned by root, not "runner"

Bug description

After building using the unity-builder github actions, the output files are owned by root.root instead of runner.docker like the files in git.

How to reproduce

Build.

Expected behavior

Files can be modified by the github actions

Additional details

The root cause here is that my build doesn’t build to build/${{ targetPlatform }}/${{ targetPlatform}}.$EXTENSION, but somewhere else, and so I want to move the output around afterwards in the github workflow rather than in the build function, but I can’t because of permissions. But it seems like, in general, this would be a better practice to run chown within the docker before finishing.

Okay, I had a little problem re-implementing #141, the license activation step was tripping up because the runner user’s $HOME wasn’t set correctly. Setting it manually to “/github/home” solves this issue: https://github.com/game-ci/unity-builder/compare/main...Bradshaw:fix-root-files-and-android

I’m now taking a look at the sdkmanager issue, and will try to solve it in a way that doesn’t require running as root

Good point. I probably should have opened this on the GH action. We can get the name, though, by passing in the result of $(whoami) or $(id).

From the workflow, while we have permissions to delete the files, a chown (or for that matter, chmod, which is what I really need) failed with “permission denied”.
