It is a second attempt to this update. First one was reverted here https://github.com/discourse/discourse/pull/8618
We noticed a problem that `like` counter had incorrect colour on mobile.
I added a missing rule to the bottom of the file (that rule existed in normalize-3 and was removed in normalize-8)
```
button,
input,
optgroup,
select,
textarea {
color: inherit;
}
```
Changelog is available here - https://github.com/necolas/normalize.css/blob/master/CHANGELOG.md
I decided that the easiest way to ensure it works would be checking different browsers. It looked good to me on Chrome, Firefox, Edge and IE 11. In addition, I checked 3 random themes.
