[New Feature] Support `.xctestproducts` and Test Plan for XCTest

[DavidAsulin1]

Hello,

I would like to suggest adding support for the .xctestproducts file in XCTest, which includes all the products necessary to execute the test. The .xctestproducts file has been added since Xcode 13.3. The main advantages of using .xctestproducts are:

• It is very suitable for executing XCTest in a pipeline.
• It supports choosing which Test Plan to execute (currently, HydraLab relies on the supplied .xctestrun file specific to one test plan).

The suggested changes are:

• Adding support for .xctestproducts.
• Adding a new option in the UI that enables the selection of a Test Plan.

These changes should enhance the usability and flexibility of XCTest.

I would love to contribute by working on the backend implementation ☺️
