fix(gateway): remove 'offline' status from DiscordUpdatePresence, as Discord only supports 'invisible' and not 'offline' (#4205)

* fix: the 'color' type on role is set to 'undefined' when its value is '0'

* fix: ensure role color is correctly assigned when value is 0

* fix: revert color type change

* fix(docs): fixed typo in big bot guide

* fix(gateway): fixed an issue which would cause bot status to appear as online if the user used 'offline' as the status

* Update settings.json

* remove offline status in DiscordUpdatePresence.status

* Apply suggestions from code review
