[a11y] Removing !important from letter-spacing marketing typography

[stamat]

What are you trying to accomplish?

Hello there! 👋

We've got like "trillion" accessibility issues for not allowing letter spacing change by the assistive plugins on dotcom marketing pages. So I would really like to solve these and remove !important on letter spacing. 🙏

I've created an override only for the /marketing/type/typography.scss file on dotcom https://github.com/github/github/pull/322450 :

1. Firstly to prove that nothing will be broken - nothing is at first glance, all other utilities with letter spacign work, order of class placement seems about right to not need !important.
2. Secondly to use as a temporary solution - but I don't really want ot use the override since it's not managable.

The only concern is that the users that might use the mktg styles might get impacted, but i think that Impact is minor, if not nonexiting.

That's about it. Do help me merge/deploy this 🙏 ❤️
