[Feature Request] Support for supplying text in multiple languages

[fiftydinar]

This would also include notifications text if notification is invoked by yafti.

Bazzite has README in 7 languages as of now, so I believe there could be some interest here from those users.

This could be done pretty quickly with gettext in the code base, but it would need to be figured out how to do this for distro-supplied manifests. I'll have a think about it while others are working on the project
