`elastic-package export` should work with any asset that packages can include

[marc-gr]

This would be a nice QoL addition since there are many assets other than dashboards and pipelines that packages can include.

Extending the export command to support them would be very helpful to prevent errors and for a better experience.

Agree, but we would need to go case by case, there are already other open issues for some assets:

• elastic-package export search #1821
• elastic-package export security_rules #2130

I will add them as subissues of this one.

Do you have some other asset in particular in mind?
