[JamieDanielson]

Which problem is this PR solving?

Backport #5412 to v1.x branch

#5031 was a large refactor for OTLP exporters, and a dependency that was previously listed as a dev dependency is now required as a production dependency. Upgrading to experimental/v0.56.0 caused an error in Yarn PnP:

2025-01-09T01:35:53.432Z   220 U Error: @opentelemetry/exporter-logs-otlp-grpc tried to access @opentelemetry/otlp-exporter-base, but it isn't declared in its dependencies; this makes the require call ambiguous and unsound.

Short description of the changes

• move @opentelemetry/otlp-exporter-base to be production dependency
