More visual bugs in the release notes widgets

[edwood-grant]

What Happened?

After doing a fix for #2224 it seems that here are more visual bugs in specific descriptions i the release carrousel widget.

Here are some screenshots as an example:

Here is for example Nimbus:

Journaler:

And Reco:

The reason is that in the last change I introduced the description to wrap and and to have a character wrap limit. And as the previous bug showed, wrapping labels in a GTk.Box will not respect natural heights for some reason. But setting them inside a Gtk.Grid will.

I'll submit a PR soon, but I set the issue to mark it as existent and refer to it on the PR.

Steps to Reproduce

1. Open AppCenter
2. Go to any application that has a long description
3. Watch the releases carrousel

Expected Behavior

The release description should not overflow the carrousel widget.
