Only show color and typography variation control if alternate variations exist

[richtabor]

#59717 added a default color/typography variation. It works well, but one follow-up would be to only show the related UI if there are additional color/typography variations available.

Visual

In the visual below, there is a "Default" color variation, even though there are no other color variations provided by the theme. This entire "Presets" UI should only render if there are alternate variations available, for both colors and typography variations independently.

Hi @richtabor, I can work on this one and would raise the PR soon.

Thank You.

Hi @richtabor, I am unable to reproduce the issue again. If you remove the variations and reload the whole site, then you would not be able to see the presets.

Can you please check at your end as well, if we are able to reproduce then I am happy to contribute to the PR.

Thank You.
