Update class_raycast3d.rst per Issue #100139

[jburt137]

Found this issue on "up-for-grabs". I been wanting to contribute to more open source projects and Godot is a very exciting project I'd like to help out with based upon my background in VFX and animation.

Please review my updates and let me know what should be changed, how I can improve the doc updates since I'm new at this. Thank you!

Hey, thanks for contributing! We can certainly use more help :)

Note that at the top of the file, it says:

.. DO NOT EDIT THIS FILE!!!
.. Generated automatically from Godot engine sources.
.. Generator: https://github.com/godotengine/godot/tree/master/doc/tools/make_rst.py.
.. XML source: https://github.com/godotengine/godot/tree/master/doc/classes/RayCast3D.xml.

The class reference (everything under classes/) is auto-generated from the XML files in the main engine repository, so you need to make any changes to the file there: https://github.com/godotengine/godot/tree/master/doc/classes/RayCast3D.xml

Please redo the changes in that file and submit a new PR in the engine repository. :)

Ah, thank you for the clarification. I was wondering about that. I didn't know if it meant just don't edit the header or what, figured I'd learn as I did the process. I will edit the xml file instead. Thank you!
