Allow inline <cite> elements

[jmsfwk]

Move the block styling and reduced font size on <cite> to only
apply when it is a child of <blockquote>.

Fixes issue #10226

This makes sense to me, but is a breaking change... can we wrap up the block form of citation into a mixin so that if someone wants to re-instate the old behavior it is as simple as

cite {
  @include block-citation();
}

Hey @jmsfwk. Thank you, I see you made the requested changes, and sorry for the late reply. I think this PR goes to the right direction, which is trying to not impose any design and simply providing a set of easily customizable tools.

It's sad I was not active when you opened this PR, I would recommand a more "component" approach rather than "allowing a old-behavior reset". Anyway, I'll take care of the changes and merge this right after.

Sorry again for the late reply.

@jmsfwk For your future pull requests, you can create a dedicated branch (like feat/optional-block-cite) and create a pull request from it. So you can continue working on your branch develop while this PR is open.

I pushed.
Now we have a .cite-block component, generated from its cite-block() mixin, and used as default (or not) for the <cite> tag according to the $enable-cite-block property.

So no migration is needed anymore, and we're slowly moving to a "component" approach for typography.
