Format the `Resource` form widget list

[pPrecel]

Description

It would be nice to have the option to customize the resources view in the resources list in the Resource Widget.

Reasons

In our use-case, a user should have the possibility to choose one gateway from the list and then save his choice in <GATEWAY_NAMESPACE>/<GATEWAY_NAME> format.

From my observations, the same use-case has ApiRule resource and ApiGateway developers decided to split resource choice into three forms. First with the namespace, second with the name, and the third displaying formatted output and passing this information to the ApiRule CR:

This solution is too complicated and not intuitive for users who expect to see possibly the same fields under resource spec and in edit mode on UI.
