[test run details] Implement Trigger mode

[jorgeepc]

Context: as part of v0.7 we want to improve the UX/UI around the Test Run Details page.

Objective: the goal of this ticket is to implement the new Trigger mode.

AC1 As a user in the Trigger mode, I want to Edit the test and Save it Note: we need to support our different trigger types (HTTP, GRPC)

AC2 As a user in the Trigger mode, I want to see the Response of the trigger request, so I can understand what happened with my test request.

Hey @jorgeepc let's add something around the expected behavior when the user clicks save, what needs to change or/and what happens next.
