Prober URLs in ProbeFailure alerts can be incorrect

float/roles/float-infra-prometheus/templates/rules/alerts_base.conf.yml alerts template says "Failed probe logs: https://https://{{ $labels.prober_float_service }}.[[ domain_public[0] ]]/" and the default for prober_float_service is 'prometheus', but e.g. for the default prober it should be 'prober'

This is because we're assuming that the service has a public_endpoint with the same name, which is not the case for the prometheus default service. There should be a way instead to retrieve the "best" public_endpoint for a specific job (via its monitoring_endpoint port, for instance)...
