melange lint action has thousands of tar errors

[xnox]

https://github.com/chainguard-dev/melange/actions/runs/8526927513

has many errors, and pages of error messages..... but lint works, and there are non red-herring issues identified in the end of the run.

I don't know if lint pipeline can be improved to be a "github checker" which does inline code comments on things it identifies.

And separately I don't understand the tar errors, possibly to do with restoring precached runs? which fails and are ignored? maybe turning off attempts to restore cache will make the build faster and have less errors.
