[ResponseOps][Rules] Adding rule.url variable (#145035)

This PR adds a new actions variable for linking back the stack
management rule page. In a future PR we will require the rule type to
specify the plugin's path when registering the rule type that way we can
link back to the specific plugin that created the rule.

Issue: #145132
