Support AsyncAPI 3 (and if possible 2) in the split command #2352
Description
Is your feature request related to a problem? Please describe.
We support split for OpenAPI 3.x only at the moment. Since we've added AsyncAPI support for lint and bundle, it makes sense to add the support to other commands.
Describe the solution you'd like
Add the support for AsyncAPI in the split command.
Describe alternatives you've considered
Doing nothing.
Additional context
We'd also benefit from adding the support in other commands.
