### Godot version

4.0.beta14

### System information

windows 10, gles 3, nvidia graphics

### Issue description

SCREEN_TEXTURE  was dropped in beta 14. The suggested replacement is to use ```uniform sampler2D SCREEN_TEXTURE : hint_screen_texture, filter_linear_mipmaps;```, but filter_linear_mipmaps is not recognized as a valid shader type hint and a shader using it fails to compile.

### Steps to reproduce

Create a canvas item shader and use the filter_linear_mipmaps type hint with a sampler2D uniform.

### Minimal reproduction project

pi.type = Variant::ARRAY;
				pi.hint = PROPERTY_HINT_ARRAY_TYPE;
				pi.hint_string = MAKE_RESOURCE_TYPE_HINT("Texture3D");
			} else {
				pi.type = Variant::OBJECT;
				pi.hint = PROPERTY_HINT_RESOURCE_TYPE;
				pi.hint_string = "Texture3D";
			}
		} break;
		case ShaderLanguage::TYPE_STRUCT: {
			
		} break;
		case ShaderLanguage::TYPE_MAX:
			break;

	return pi;
