pango: update to 1.51.2, enable tests
https://github.com/void-linux/void-packages/pull/48712

Description:
@cinerea0 

`pango` devs dropped even/odd versioning. `1.51.*` is considered stable now.

read the section `Versioning` (it was added 3 moths ago) of the `README.md` - https://gitlab.gnome.org/GNOME/pango

> Historically, Pango was following the traditionally even/odd library
versioning scheme where stable releases are marked by even minor
and development releases by an odd minor.
In recent years, Pango development has slowed down so much that it
no longer makes sense to have unstable cycles, or even unstable releases.
Going forward, pango versions will simply be increasing triples, with
no particular significance to the parity of the minor version.
