### 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

N/A
DataType nc = p_op->arguments[2]->get_datatype();
			valid = na == TYPE_BOOL && (nb == nc);
			ret_type = nb;
			ret_size = sa;
		} break;
		default: {
			ERR_FAIL_V(false);
		}
	}
	if (r_ret_type) {
		*r_ret_type = ret_type;
	}
	if (r_ret_size) {
		*r_ret_size = ret_size;
	}
	return valid;
