Revisit runner-helper alpine image creation
The fix for Gitlab runner helper base image vulnerabilities (#29642 - closed) (Address vulnerability reports against runner-he... (!3958 - merged)) involved both manually installing packages and using alternate package repositories. Ideally this is a temporary solution until the CVE issues are fixed upstream. We should revisit the changes in Address vulnerability reports against runner-he... (!3958 - merged) at some future point to see if theya re still necessary. For example, We plan to drop support for alpine
3.12
and 3.13
in %16.0; that might be a good time to revisit. Dropping support for 3.14
will follow shortly an that will be another good opportunity to revisit, especially considering many/all of the critical
vulnerabilities in Gitlab runner helper base image vulnerabilities (#29642 - closed) were agaisnt the 3.14
release.
