Subject: [PATCH] Retry failed repo builds (#21)

We had failed repo builds quite often recently which causes manual effort.
Let's try to mitigate this using retry logic.

Taken from https://github.com/gardenlinux/repo-debian-snapshot/tree/main/.github/workflows

Fixes https://github.com/gardenlinux/gardenlinux/issues/2288
(hopefully)
