Split alerts/alerts.libsonnet into one file per collector under alerts/, like kubernetes-mixin. Each rule is a plain Prometheus alerting rule with the PromQL written out in an expr block and %(name)s placeholders for the _config values; lib/alerts.libsonnet keeps the collector and per-alert gating and keep_firing_for. The pagefile, diskdrive and license alerts get groups of their own so that one file is one group. The rendered default rules are unchanged apart from expr block scalars.
