CharacterBody2D "move_and_slide" method description should have a warning for floating character bodies

[kassheart]

Your Godot version: 4.7

Issue description: The "move_and_slide" method description for "CharacterBody2D" says that it modifies velocity when a slide collision occurs which just isn't true for floating character bodies, as the velocity stays the same no matter what unlike grounded character bodies

I think this should be clear enough from the "(by default only on floor)" and the descriptions in motion mode, I don't think this should be duplicated to there:

Apply when notions of walls, ceiling and floor are relevant. In this mode the body motion will react to slopes (acceleration/slowdown). This mode is suitable for sided games like platformers.
