Evolution: Somehow provide help

For reasons (https://gitlab.gnome.org/GNOME/evolution/issues/804#note_724176) and offline viewing, maybe it would be nice if evolution-help is installed/installable somehow.

Can you do it / add instructions for it?

Bugs should be reported at https://github.com/flathub/org.gnome.Evolution as not every app maintainer uses Discourse.

Good call https://github.com/flathub/org.gnome.Evolution/issues/21
