Fix Divider component color prop name and values

[PelayoFelgueroso]

Describe the bug
The Divider component accepts the following values for the color prop: lightGrey | mediumGrey | darkGrey.

However, the resulting color is not always grey, since it relies on the neutral color token. It will usually be a shade of grey, but not necessarily.

Expected behaviour
The accepted prop values should not include the word “grey” or any specific color name. Consider renaming the prop to color-weight and allowing only: light | medium | dark.

Screenshots
If applicable, add screenshots to help explain your problem.
