Search finds apps with no installation candidate

[benmordecai]

Multiple times I have searched and found appimages and then when I sent to install I got no installation candidate warnings.

Example:
zap search nextcloud
zap install nextcloud

That's unfortunately because https://github.com/AppImage/appimage.github.io/commits/master/apps/Nextcloud.md hasn't been updated in a long time - and - https://appimage.github.io/Nextcloud/ (and here https://github.com/AppImage/appimage.github.io/blob/master/data/Nextcloud), does not have a download button.

And hence, zap uses this index to download and provide metadata.

You will have to, pass the URL manually

zap install --from <url_to_nextcloud_appimage> nextcloud
