Change the label of the Night colour scheme to append “(low contrast)”

Problem/Motivation

One of the supplied colour scheme uses low contrast colours.

This is by design as it represent a low light colour scheme. However, the label of that colour scheme should be appended with “(low contrast)”.

Steps to reproduce

Select the Night colour scheme and notice the low text colour contrast.

Proposed resolution

Change the label of the Night colour scheme to append “(low contrast)”.

That way, we indicate that the low colour contrast for that colour scheme is intended.
