Missing release for opentelemetry_broadway 0.3

[hoyon]

The opentelemetry_broadway library was bumped to 0.3 in this PR however the latest version on hex.pm is 0.2.0 https://hex.pm/packages/opentelemetry_broadway. Can these new changes be released to hexpm?

Would be good to get this version released which included updates to the opentelemetry_semantic_conventions dependency allowing it to be used without using override.
