With Prometheus v3 [histograms are normalized](https://prometheus.io/docs/prometheus/latest/migration/#le-and-quantile-label-values) and this breaks rules that select on the `le` label. This PR overwrites the label selectors that [mixin](https://github.com/kubernetes-monitoring) usese. Before: ``` {le="1"} ``` Now with Prometheus v3: ``` {le="1.0"} ``` This will break set ups with prometheus v2. However, I think it is still an improvement by default Prometheus v3 is used and I would expect that the generated rules are workind with the default Prometheus version as well.
