[9.x] Update schedule:list colouring output

[bert-w]

I noticed that the colouring of the parameters was slightly off for the php artisan schedule:list command. I changed the regex to mark everything yellow after the command name. Note that I am assuming that command names consist of the following syntax: [\w\-:]+, meaning: word-characters (i.e. [a-zA-Z0-9_]), dashes - and/or colon :.

Before and after:

I guess it would be nice to highlight 3 and 60 separately but that increases the complexity for little benefit.
