Replace axes colors in image

[BLooperZ]

This fixes #10765
The colors in the modified axes image now matches the colors in editor

Modification process:
I have swapped the green and blue color channels in the image
then optimized it using the same command from #5254

Thank you

The change itself is good but please convert this image to a webp file. You can find information on doing that in our documentation here: https://docs.godotengine.org/en/stable/contributing/documentation/docs_image_guidelines.html

Not only the axes colors don't match Godot, but also the orientation of the Z axis. The current image shows a left-handed coordinate system but Godot uses right-handed coordinate system. See: https://docs.godotengine.org/en/4.4/tutorials/3d/introduction_to_3d.html#coordinate-system.

Corrected:

And BTW the rotation direction indicators are easy to misinterpret (the solid/intersection part goes behind or in front of the given axis? 🤔 (answer: assuming X/Y rotation directions are shown correctly, the solid/intersection parts are behind the axes)). So would be nice if they could be improved. But that would be a bonus / shouldn't be necessary.
