:bug: (Bug Fix)

• fix(core): align inconsistent behavior of getEnv() and getEnvWithoutDefaults() when a process polyfill is used #4648 @pichlermarc

  • fixes a circular import warning which would appear in rollup when bundling @opentelemetry/resources
• fix(exporter-metrics-otlp-grpc): add explicit otlp-exporter-base dependency to exporter-metrics-otlp-grpc #4678 @AkselAllas
