Pratik Mankawde a1d7b18ce1 fix(telemetry): drop redundant OTTL copy of service.name for cloud labels ...

Grafana Cloud's OTLP ingest already promotes the `service.name` resource
attribute to a `service_name` metric label. The `transform/cloudlabels`
processor was ALSO setting `service_name` as a datapoint attribute,
which Mimir treats as a duplicate label and concatenates as
`service_name="xrpld;xrpld"` on every series. Dashboards filtering on
`service_name=xrpld` then returned no data.

Remove the redundant `set(attributes["service_name"], ...)` line and
add a comment documenting the doubling. `service.instance.id` does not
exhibit the same behaviour, so that copy is retained for the $node
filter to keep resolving.

Reintroduces the pre-e76eed5296 shape (which was correct on this label)
without reverting that commit's other cloud-label fixes.
