🖊️ Color "grey" is not accepted

[MarleenGilsing]

In the turtle 'gray' (American English) is accepted as a color, but 'grey' isn't eventhough that's the correct Brittish spelling.

While we're on it, you can't use the command 'colour' either, but that might be a bit more difficult to change?

Hi @MarleenGilsing!

Not very hard to change, maybe a bit of an issue since in Python, these thing also will not work. (in fact changing colour is easier since we already support multiple versions of a keyword, but grey goes straight to Python :) )
