Changed the wrong word in color & dark mode custom component

[sabernhardt]

The toggle button can appear in either the bottom-right or bottom-left, depending on language direction.

The theme setting could clarify the two corner positions, as in the support article, or else the setting text could change to "bottom corner" for simplicity.

In 52211:

Twenty Twenty-One: Correct description of Dark Mode in the Customizer.

The Dark Mode toggle can appear in both bottom corners. This removes “right” from the description to be accurate for both RTL and LTR languages.
