Add Support for Xcode 15 and iOS 17

We are trying to use xctestrunner to run testing on iOS 17 devices with xcode 15.0

We are running into the follow errors when passing a command:
First when running the following command:
`ios_test_runner --app_under_test_path ios-configurator.ipa --test_bundle_path ios-configurator-ui-tests.zip --work_dir ~/ios_test_runner_work_dir --test_type xcuitest test --id 00008020-001524340281002E`

we get the following error regardless of what iOS our device is on:
```

xcodebuild: error: Failed to build workspace temporary with scheme Transient Testing.: File is of an unsupported type; must be either an xctestrun file or xctestproducts bundle.
```

I am able to fix this issue by manually changing the name of the `xctestrun.plist` file to `test.xctestrun` and rerunning the command:
`/Applications/Xcode15.0beta3.app/Contents/Developer/usr/bin/xcodebuild test-without-building -xctestrun ~/ios_test_runner_work_dir/TEST_ROOT/test.xctestrun -destination id=00008020-001524340281002E -derivedDataPath /var/folders/6d/l0ggp9fj52g22q3x1ghl7bfh0000gq/T/tmp73pv379u -resultBundlePath /var/folders/6d/l0ggp9fj52g22q3x1ghl7bfh0000gq/T/tmp73pv379u/test1.xcresult -collect-test-diagnostics=never`

After doing this we run into another error:
```

We do not run into this second error with iOS 16, only with iOS 17.
