Previously, there were three different DTDs used. Let's switch to a single one.
We will go with 4.5, since it is latest version that does not have any backwards incompatible changes.
With the instance infrastructure, we can go from
the ID of a running application to its monitor PID,
so we can accept the application ID here. Whats more,
we can offer completion for it.
Note that completion only works if you use sudo -E,
since the flatpak used for complcations needs to see
the session environment to find running instances.
Closes: #2181

The --verbose and --ostree-verbose options are global to all
subcommands, but --version can only be used with the main "flatpak"
command, so fix the man pages to reflect that.
This completely regressed, and it seems complicated to fix it without
requiring extra privileges. So, the new version requires you to sudo
to run it, which is not great, but at least it makes it work for
all cases.
