setup-apkrepos: Does not overwrite past selection.
This is three issues in one.
The first issue is that x64/i386 is not replicated to all mirrors. In fact I noticed that most mirrors fail to mirror all of the builds.
That goes to issue #2 with setup-apkrepos.
After running it the first time, it errored out with a file not found error due to the mirror not having the build. When running it a second time, and selecting 1 (the main repo), it does not actually overwrite the configuration and attempts to pull from the previously selected repo.
The third issue is that if this script fails, it does not stop the main setup-alpine script (or retry with new input) from running and can hide the first issue.
