Fabian Homborg d79f864072 Add a note for help thing to the missing doc error message
This should cover most cases - the user didn't install the docs and is
trying to view the man page via __fish_print_help, so we don't have a
way to show anything.

But `help thing` will fall back to the online version of the docs,
which should work if there's an internet connection.

See #7824.
