Freecodecamp: Add support for British version of gray

[snigo]

Describe your problem and how to reproduce it:
As per this forum post we need to add support for British grey in Basic CSS: Create a custom CSS Variable challenge as it's totally valid.

Also test regex might be slightly improved to ensure proper syntax:

/\.penguin\s*\{[^{}]*?--penguin-skin\s*:\s*gr[ae]y\s*;[^{}]*?\}/

[RandellDawson]

The instructions tell the user the value to accept, so there is no need to change the tests.

In the penguin class, create a variable name --penguin-skin and give it a value of gray.

I agree with Randell, it explicitly says to use "gray" - what about the hex and rgb values of gray? I don't think we need accommodate for any of these when it says exactly what to use.

[ojeytonwilliams]

I'd say accept both values. Someone using the British spelling hasn't misunderstood the challenge. They've taken the time to type an answer, rather than just copy-pasting. Given that grey and gray are equivalent in this context, nothing of consequence changes.

[snigo]

Yes exactly, it’s not a matter of changing instructions, rather the matter of user experience in case they make this valid typo

[moT01]

I still don't think it's necessary, but I suppose there isn't any harm in it either. So I'm fine with it either way.

[RandellDawson]

@Manish-Giri @thecodingaviator Can we get your input here? We have two for and two against allowing "grey" in the test.

[thecodingaviator]

Instead of checking for grey or gray why not check the rgb of the elements?

[LarryHu0217]

I can help this one. Do we need to change grey to gray?@RandellDawson

[RandellDawson]

@LarryHu0217 Nothing has been decided yet. Still waiting on some other mods to chime in.

[ahmadabdolsaheb]

Although I agree with @RandellDawson and @moT01, it would not hurt to add gery to the test since some users are genuinely getting confused.

I'm fine with it either way.

[RandellDawson]

OK, someone go ahead and create a PR to allow either grey or gray.

[Pallof]

Is anyone currently working on this? If not, may I take a go at it?

[moT01]

Go for it @Pallof 👍

[deepgoonumich]

Me and my colleague @manrajtoor also worked on this for a school project. Should we submit a pull request still or is it too late?

[ojeytonwilliams]

Hi @deepgoonumich, the existing PR has already been accepted and will be merged once the code freeze is over. So, yes, it's too late for this one!

There are some new issues with the help wanted label. I would take a look at https://github.com/freeCodeCamp/freeCodeCamp/issues/38589 and https://github.com/freeCodeCamp/freeCodeCamp/issues/38606
