wall_min_slide_angle : incorrect use of slope instead of wall

Issue description:
Hello,
It appears CharacterBody3D and CharacterBody2D have a faulty description for the wall_min_slide_angle parameter :

Minimum angle (in radians) where the body is allowed to slide when it encounters a slope

It should be wall instead of slope.. I 've put this parameter to 60° in my game because we have big slopes, but it just almost removed the sliding along the walls.
