Read the documentation, maybe we already have the feature

Is your feature request related to a problem? Please describe.
List of standard inline matchers seems incomplete, we have any-*, but we don't have anything for collections, arrays or maps.

Describe the solution you'd like

I'd be glad to see something like:

{"foo": [1, 2, 3]} matches {"foo": [#{json-unit.any-int}...]} or {"foo": #{json-unit.array-of-int]}

Describe alternatives you've considered
Sure there's alternative to write a custom matcher or to just use assertions.

But this doesn't solve for example issue with MockServer, which supports inline matchers only
