Feature (content): Include examples for sign-in and sign in
It's a common error to confuse "sign in" (verb) and "sign-in" (noun) in our documentation.
Based on gitlab-org/gitlab!46500 (merged), I realize that the error can extend to our UI. So I propose adding this section to our Pajamas terminology page.
I'm not sure about my approach; I could reorganize this MR to put "sign in" and "sign-in" in the noun and verb sections. But at first glance, I think the direct contrast is more effective.
