[bug#51428] [PATCH core-update-frozen 03/13] gnu: at-spi2-core: Reverse inheritance relationship with minimal variant.

[Maxim Cournoyer]

Since the minimal variant is here to stay, this should make things easier to
maintain.

* gnu/packages/gtk.scm (at-spi2-core-minimal): Rewrite after removing
inheritance, making it the base minimal package, with no documentation-related
inputs or build phases.
(at-spi2-core): Rewrite definition, inherit from the above minimal variant,
adding the documentation-related inputs and build phases.
