Basis.Rotated doesnt give the same value between GDScript and C#

### Tested versions

This was tested in godot 4.2.1 mono and standard build (for GDScript)

### System information

Windows 11, 4.2.1 stable, Vulkan Forward+

### Issue description

I am creating two vectors, one for pos, one for rotation. And i'm getting the transform out of that pair.
The resulting transform is correct on GDScript, and Incorrect on C# for some reason.

Outputs are
```
C#: [X: (1,1046701E-06, -0,99999994, 0), Y: (0,99999994, 1,1046701E-06, 0), Z: (0, 0, 1)]
GDScript: [X: (0.000001, -1, 0), Y: (1, 0.000001, 0), Z: (0, 0, 1)]
```

I think it all comes down to underlying types (I read somewhere that GDScript floats are 64 bits, whereas C# floats are 32),
or I might have missed something in my examples.
Please provide my poor brain with answers
Best regards
I attached a MRP.

### Steps to reproduce

Just run the MRP to get a perfect repro

### Additional insights

Just for going further, I put the code that transform two Vector3 given in params and outputs a transform in gdscript, that i called from C#, and interestingly, the result was similar to the one i got in native C#. Which definitely goes in the direction of wrong underlying types.

Start by downloading and running the attached GDBUG.zip minimal reproduction project, then compare the C# and GDScript transform outputs described in the issue. Trace how the two Vector3 values are converted and how the transform is produced; done means identifying and correcting the source of the differing results, with the reproduction confirming consistent output.
