The --app and --runtime options are not really useful
for flatpak info, since you need to specify a full ID
anyway, and it is highly unlikely that you will have
ID clashes between apps and runtimes. Also, the options
are documented in a confusing way.
For a few commands the options aren't fully documented. This commit
makes the manpage documentation (almost) match the options shown
when you run "<command> --help" on the command line.
- Fix typos in doc/flatpak-install and doc/flatpak-update.
- The commands ending in -app were deprecated in commit f7a1fdaa,
so update a few remaining references to them.
- flatpak-update is used for runtimes and applications, so fix its short
description.
