Fix-test-suite-not-run-on-macos (#6631)

Fixes to run test_suite.yml during macos CI (if "test suite mac" label is present).

* Make sure the Contents/Frameworks folder is created.

* Set WEBOTS_HOME_PATH such that tests can find Makefile.include during CI.

* Change WEBOTS_HOME to Webots.app and add logic to test_suite.py to find webots executable.

* Get qt_warning_filters.conf from correct location on macos.

* Ignore (but warn about) error trying to connect to background Webots on MacOS.

* On Mac, timeout test after 60 minutes instead of 10.

* Use macos-13 runner instead of macos-14. The former has twice as much RAM as the latter.

* Install urdfdom during macos CI because it is needed by tests suite.

* Assert that move succeeds.

* Print age of ode_tmp.dif so we can see how long we should wait on macos during CI.

* Allow up to 20 seconds for world reload.

* Skip billboard.wbt test during macos CI. The test passes locally, so the failure is presumably due to the CI server being headless.

* Only increase timeout on macos.
