Misleading or incorrect documentation for move_local_x and move_local_y functions

[RiQuY]

Your Godot version:
4.5.stable

Issue description:
The documentation of the move_local_x and move_local_y functions are misleading or incorrect.

The docs say the following:

Applies a local translation on the node's X axis based on the Node._process()'s delta. If scaled is false, normalizes the movement.
Applies a local translation on the node's Y axis based on the Node._process()'s delta. If scaled is false, normalizes the movement.

Checking the C++ source there isn't any place where Node._process() delta is used, the function just changes the position of the Node based on the number passed through the delta_p parameter.

Tests:
Thanks to Sniffi on GDQuest Discord for providing tests.

Suggested solution:
The description of both functions should be changed to something like the following, removing the mention of Node._process() delta:

• move_local_x(): "Applies a local translation on the node's X axis by the delta amount."
• move_local_y(): "Applies a local translation on the node's Y axis by the delta amount."

I didn't open a PR because I'm not sure in how many places or repositories this change needs to be applied.
