The `:not(.docs-card-container) .docs-card` selector was meant to give
standalone cards a vertical margin, but no element has the
docs-card-container class, so it matched every card. Cards in a grid
without a header picked up the 1rem margin on top of the 1.25rem grid
gap, leaving rows 52px apart while columns are 20px apart (for example on
/reference/migrations, /guide/i18n and /roadmap).
Apply the margin only to cards that are not direct children of a card
grid.
(cherry picked from commit b9cbc5fbbe)
Updates the Playground card copy and adds a `titleInline` attribute on
<docs-card> so the icon and title sit on the same row. Existing cards
are unaffected.
To increase the ease of development we are moving @angular/docs into the adev directory within this repo. While
we are doing this to improve our development experience in the short term, efforts are also in place
to maintain a division between this @angular/docs (shared) code and adev itself, so that it can be extracted
back out in the future when components is ready to leverage it as well.
