Add to app store

[jancborchardt]

@violoncelloCH @MorrisJobke @rullzer @nextcloud/user_external we should probably put the app in the app store, right?

@violoncelloCH do you want to do that? :)

[violoncelloCH]

Yes, I will try to do this. (Will maybe need some guidance.)
I'm actually reading the documentation on how to publish an app to the appstore :)

I primarily struggled with the permissions, because the occ integrity:sign-app command needs to be run as www-data, but www-data doesn't have access to the private key, which is saved in my primary user's home directory on my laptop.

The other thing I didn't expect is that occ integrity:sign-app also adds the files in the hidden .git/ directory into signatures.json and there is (AFAIK) no option to exclude this directory. So the only way is to copy the whole folder of the app to another location and then remove .git/ as well??
(For tar i can simply do --exclude .git/)

I now added the first release to the appstore and hope it worked. I guess it simply takes some time or need some manual steps on your (nextcloud's) side? There was no real feedback except a spinning circle on the "Upload" button. The form stayed with the content filled in after the spinning circle disappeared again. Maybe that could be improved in terms of UI design. Also an information text for the first time uploader about when he can expect the app/release to be visible in the appstore would be nice.

If I'm right, I can't set an individual publisher for each app, so the only way to set it to Nextcloud would be to set my whole appstore account to the name "Nextcloud". Should I do this?
