Use the matrix identifier to name the "Check Certificates" workflow jobs

When no name is provided for a matrix job, the workflow job is named according to the contents of
`jobs[].<job_id>.strategy.matrix[]`. That can result in some fairly cryptic job names when the matrix contains a complex
data structure as is the case here. We already have a string to uniquely identify each certificate to humans, which is
exactly what the `jobs[].<job_id>.name` property does for jobs, so it will be an improvement to name the jobs according
to that identifier.
