Describe the bug

After upgrading hydra to version 2.2.0, we receive in our opentelemetry collector the deployment.environment key as empty. We have set in hydra the following env vars for otel config:

TRACING_SERVICE_NAME="hydra"
TRACING_PROVIDER="otel"
TRACING_PROVIDERS_OTLP_INSECURE=true
TRACING_PROVIDERS_OTLP_SAMPLING_SAMPLING_RATIO=0.4
TRACING_PROVIDERS_OTLP_SERVER_URL="otel:4318"
OTEL_RESOURCE_ATTRIBUTES="service.name=hydra,deployment.environment=stg,service.version=2.2.0" 

In the collector, we receive the attributes as follows:
Resource attributes:
-> deployment.environment: Str()
-> service.name: Str(hydra)
-> service.version: Str(2.2.0)

Reproducing the bug

In hydra v2.2.0, set the following env vars:

TRACING_SERVICE_NAME="hydra"
TRACING_PROVIDER="otel"
TRACING_PROVIDERS_OTLP_INSECURE=true
TRACING_PROVIDERS_OTLP_SAMPLING_SAMPLING_RATIO=0.4
TRACING_PROVIDERS_OTLP_SERVER_URL="otel:4318"
OTEL_RESOURCE_ATTRIBUTES="service.name=hydra,deployment.environment=stg,service.version=2.2.0"
