Describe the bug

The test discovery fails on CS test suites during editing. The guard is expecting script type GDScript where is failing for CSharpScript type.

Dev Hints

res://addons/gdUnit4/src/core/discovery/GdUnitTestDiscoverGuard.gd

func discover(script: Script) -> void:
    if GdObjects.is_test_suite(script):
        # a new test suite is discovered
        if not _discover_cache.has(script.resource_path):
            var scanner := GdUnitTestSuiteScanner.new()
            var test_suite := scanner._parse_test_suite(script)

The parser expects GDScript and do fail by

res://addons/gdUnit4/src/core/discovery/GdUnitTestDiscoverGuard.gd:27 - Invalid type in function '_parse_test_suite' in base 'RefCounted (GdUnitTestSuiteScanner)'. The Object-derived class of argument 1 (CSharpScript) is not a subclass of the expected argument class.

Steps to Reproduce

• open a CS test suite
• edit and save
