Renovate's Repology datasource stopped resolving Alpine package pins
across the organization, so every alpine_3_24/* lookup returned no
result and pinned packages were no longer updated at all.

Switch the Alpine custom manager to a custom datasource that reads the
Alpine CDN directory listing directly, using extractVersionTemplate to
pull the version out of each .apk filename. libnsl-dev lives in the
community repository and gets its own registry URL, since custom
datasources only consult the first registry.
