fix(aci): Add an initial UptimeSubscription serializer (#92150)

Add UptimeSubscriptionSerializer to allow Detector endpoints to return
successfully.
Detector data source subscription types need to be serializable for the
detectors APIs.
Add a test to verify that we can return a serialized uptime detector;
the specifics of the fields serialized are more a question for uptime
folks and not yet relevant, so the serialization result contents are
left untested.
