[docs] Remove blank lines

Any particular reason? They help with readability, and removing them doesn't save any meaningful bytes.

If I remember the discussion correctly then it was about consistency. I don't have a strong opinion either way. However, if the goal is consistency then adding blank lines between tags could potentially hurt readability as the number of tags grows.

Though from experience I'd advise against arguing about formatting that requires human interaction. I don't remember the pre-prettier days very fondly 😉

Suggested change

	1. `key` (_String_ | _Number_): A breakpoint key (`xs`, `sm`, etc.) or a screen width number in px.

Should we make these px?

[oliviertassinari]

They are already px?

[oliviertassinari]

Or did you mean px vs px?

[mbrookes]

Yes, px rather than px?

[oliviertassinari]

Sounds fair, why not

Regarding @tags, we can find a discussion about it on: #22447 (comment). I'm using the new convention we went with.
