Ability to set resource attributes on the telemetry trait

[lsergio]

Requirement

As I developer, I wish I could add resource attributes to my telemetry spans using the the telemetry add on trait. Currently I can do it using the camel trait:

camel:
  runtimeVersion: 3.2.3
 properties:
  - quarkus.otel.resource.attributes=service.name=My Service,product=My Product,tenantId=123

Problem

There isn't a field in the telemetry trait to do so

Proposal

Include a resourceAttributes field in the telemetry trait.

Same as expressed in #6002 (comment) - I think that we should avoid just translating camel properties in the future in order to be able to simplify long term maintenance.
