Issue description

As described in this closed issue, the settings for anisotropic filtering have changed in Godot 4.x.

It seems that the latest documentation does not describe these changes. For example, the Texture2D import settings still reference a setting that no longer exists. I believe there are no instructions in the tutorial on how to change the anisotropic filtering settings or how to enable the correct Sampling Filter on a material to use this feature.
