Publish Inugram in F-Droid

[the-nexi]

Please consider publishing Inugram on F-Droid.

This would make installation and updates easier for users who rely on F-Droid, while also providing an independently built version from the published source.

Forkgram and Mercurygram already provide F-droid builds, so their CIs may be used as a reference.

i am too lazy to bother with f-droid packaging. im not against it, i just dont feel the need when a) the app self-updates, b) if you dont like the app self-updating you can just use obtainium + github releases.

feel free to open a pr or whatever though!
