[website] Add F-Droid and flathub download links to main home page

[rugk]

Is there an existing issue for this?

• I have searched the existing issues

Pain

I tried to find a convenienz download link. However:

• instead of an F-Droid link I only found an apk link, I am not going to install that
• instead of a Flatpak, I found some .deb or .rpm files

Later i found https://spotube.krtirtho.dev/other-downloads/package-manager but I would have given up before if I did not knew it existed.

Suggested solution

Add the download links/badges to your Readme more prominently.

Useful resources

F-Droid: https://fdroid.gitlab.io/artwork/badge/get-it-on.png (the one currently used looks outdated)
Flathub: https://flathub.org/badges

Additional information

Edit: Ah found it in the Readme, you have to scroll down so much well… (on my phone I did not do that hehe) anyway on the website it is even less obvious.
