Change description and summary for the RadixAppComponentCrashLooping alert

[nilsgstrabo]

The description and summary saying that a component is crash looping is technically incorrect, as a single crash (and not a crash-loop) will also trigger the alert. We got a question in Slack about this https://equinor.slack.com/archives/CBKM6N2JY/p1736154938640989

I suggest we change the summary field to Component crashed and description to Component {{ $labels.label_radix_component}} in environment {{ $labels.label_radix_env }} for application {{ $labels.label_radix_app}} has crashed {{ printf "%.2f" $value }} times / 10 minutes

Alert spec:

radix-flux/components/third-party/kube-prometheus-stack/chart/helmRelease.yaml

Lines 197 to 198 in 62c6444

	description: Component {{ $labels.label_radix_component}} in environment {{ $labels.label_radix_env }} for application {{ $labels.label_radix_app}} is restarting {{ printf "%.2f" $value }} times / 10 minutes.
