When installing plone.app.discussion enable comments globally.

In 6.1 you have to explicitly install the add-on in the Add-ons control panel.
If you do that, then you obviously want discussions to be enabled globally.
I think this also helps for the Volto case, where a Discussion control panel is missing, so in Plone 6.0 you cannot even properly enable comments.

 Move this package in the space of Plone Core add-ons.
 It now depends on Products.CMFPlone and is no longer installed by default.
 It is still available in the default Plone distribution, but can be omitted in customizations.
