Leverage GUT XML Output

[RGonzalezTech]

Summary

The new GUT versions do not output the results the same way and are causing false negative results. Using the XML output to determine $TESTS and $FAILED. See Original Issue #22

Details

• Upgraded GUT to 7.4.1
• Add XML parameter to $RUN_OPTIONS
• Read the XML file and set values from for tests= and failures=

reviews #22

[RGonzalezTech]

Included some parsing for the check_by_asserts function as well. The output XML filename can be defined as a new action input in case it needs to be used with direct-scene.

Concern

See merged PR for more details. Not sure how the -gjunit_xml_file= arg will interact with the -gconfig= input on:

godot-tester/entrypoint.sh
