Update Nick Colours for v4.4.0

PR #4649 update #chat.colored-nicks CSS selector.

You should probably adapt the theme so that only the new selectors remain.
The old ones aren't useful once we release the new TL version.

As for the commit messages, it isn't a regression but a change that was done on purpose, so please reword that ;)

It was a regression for the morning theme, as there the change was forgotten originally. It isn't for normal themes that just update for the new version of the code.

Get rid of that comment, it isn't useful in the future for readers of the code.
They will be working with the latest version.

This doesn't just update the selector, but completely modifies the colors.
This is unexpected, all it should be doing is change the selector based on the commit message

[brunnre8]

This needs to be fixed up to do the minimal changes necessary

[aab12345]

So it should be (example)

.user.color-1 { color: #ef4657; }
.user.color-17 { color: #ef4657; }

.user.color-2 { color: #ff93a4; }
.user.color-18 { color: #ff93a4; }

etc etc ? I think I got it this time, correct me if I'm wrong again.

No, there's no need to duplicate the color.
Simply delete every occurrence of #chat.colored-nicks and leave the rest alone
