hi @jenniferplusplus, I'm from bullmq team, I justo saw this other package https://github.com/appsignal/opentelemetry-instrumentation-bullmq were you appear as a contributor. Wondering where I should continue contributing?

[jenniferplusplus]

That's a fork of this project. They're trying to get this instrumentation included in the official otel contributors repo, and I've been waiting to see what happens before I do anything with this one.

One of those project will likely be more actively maintained, and I plan to deprecate this one in favor of that. But for now I'm waiting to see which one it will be. I'll keep doing maintenance and accepting enhancements on this project until then.
