OpenTelemetry | bugfix: specify resource creation to use Schemas.V1_25_0

[keith-decker]

Relevant issues

If LiteLLM is installed in a custom container/pod and openetelemetry is installed with a different version, then the gen_ai attributes do not align with the future versions of semconvs. Specifying the schema version here tells the backends to use the semconvs version this was written against.
