chore: move anomaly detection rules to jsonnet

This migrates the anomaly detection rules from a regular yaml to jsonnet. Doing this allows us to inject extra selectors. As a result we can separate the rules by environment in Thanos.

In gitlab-com/gl-infra&1107 (closed) we can take this one step further and separate by service.

While doing this, we also remove the dependency on the 1m burn rate that we intend to remove, and rely on the 5m burn rate and 1h burn rate instead. The recording rule names remain the same. Doing this using jsonnet and passing in the aggregation set should also help us reusing this for the migration to Mimir.

Not using the 5m burnrate for these solves gitlab-com/gl-infra/platform/runway/team#169 (closed)
