docs-bug(Theming): Reading hues from palettes

[Lepmim]

Documentation Feedback

The documentation in the chapter Reading hues from palettes suggests to use strings as the hue's number identifier: background: mat.get-color-from-palette($my-palette, '500');

It seems to only work with number input though: background: mat.get-color-from-palette($my-palette, 500);
