Maintainers Growth WG: Define OKRs

[smoya]

The Maintainers Growth WG decided to focus its efforts on https://github.com/asyncapi/website/issues/2992. At this point, we know what we want to do regarding tasks, but the results we expect are just rough ideas.

In the past, we talked about increasing the number of non-Postman maintainers. And it seems, based on last conversations during our meetings, that we are still interested in such an objective. However, I'm opening this issue so we all can discuss this or any other objective we think we should pursue, to end defining its key results along with the metrics we want to track.

I suggest the outcome of this issue should be a clear definition on the objective we pursue (even if its temporary), and a list of key results (we can follow OKR model or any other), ideally along metrics we should track in order to evaluate the success and achievement of such an objective.

I call all WG members and all interested people to share your ideas and opinions and suggestions.
