Suggestion: `fs-normal` to set font-size to its "normal" (i.e. body) value about bootstrap

This would be .fs-6 by default in the docs. And there's no font-size: normal value in CSS, so we don't provide a utility like that.

We could maybe do a .fs-body or something, but that might just be duplicative of what we provide with .fs-6.

Yeah, that's a good point against calling it -normal!

On the other hand:
If you override the default font-size by setting:

--bs-body-font-size: 1.2rem;

then .fs-6 still results in 1.0rem.
So what would be nice would be a way to do something like <h1 class="fs-body"> which resets the size to the "normal" body size.
