Closed issue by DarthWound on void-packages repository

https://github.com/void-linux/void-packages/issues/13544

Description:
Some users have the `google-fonts` package to have correct webfonts everywhere, putting `fonts-roboto-ttf` as a dep for [plata-theme](https://github.com/void-linux/void-packages/blob/master/srcpkgs/plata-theme/template) makes it impossible for them to install it.

Roboto is recommended by upstream but not mandatory, and the GNOME-Shell CSS has a fallback to sans-serif if Roboto isn't installed. Maybe just a message during install is enough.

_PS: `plata-theme` package is [outdated](https://gitlab.com/tista500/plata-theme/-/tags) btw :) except if you only want to provide "commercial releases" and not the "maintenance" ones._
