Add CI check that ensures all contrib packages are in the OTel registry

[rauno56]

Describe the solution you'd like to see

OpenTelemetry org keeps a registry of all the compatible packages. Since it's managed in a separate repo and process people are often not even aware that exists or forget to add new packages there. We could either

1. implement a check that warns/errors when a contrib package is not in the registry,
2. implement a check that opens a PR in the registry with newly added packages that come with certain fields in package.json.

I'm contemplating adding up-for-graps to labels ignored by stalebot.

I generally think issues nobody wants to work on should eventually be closed and forgotten until they rise again for good hygiene, but good first issues also serve another purpose - welcoming newcomers.
