add regex whitelist to no-arbitrary-values

[ginasummation]

Pull Request Name

Add a whitelist for no-arbitrary-values rule

Description

I'm using the no-arbitrary-values rule to enforce team consistency with a design system. Our design system is not opinionated on a subset of tailwind classes though (mostly height and width related) so I would like to whitelist those sort of classes to allow for arbitrary values. See similar asks from these two issues

I added a unit test with various whitelist options to make sure the change works. I also made sure the regex would allow users to specify the content within the arbitrary values. I,e whitelisting 'text-[12px]' but disallowing 'text-[#ffffff]'
