The GtkListBox::row-activated signal only emits when
a row is activated, not the child widget. This means,
the check button wouldn't trigger the emission of

NewBottleDialog:selected-environment property.

appdata: translate=no properties

It appears that the appstream project no longer supports `translatable=no` properties, and gettext extract the `translatable=no` marked strings as translatable.

I opened an issue to inform about the situation, but `translatable=no` properties are not accepted by developers. You can find the issue here: https://github.com/ximion/appstream/issues/623

This is important to have because complex toggles require slightly
different parameters.

This reverts commit 91e2798c.

* Move non-obvious code blocks into methods to better describe why it is needed

* Only show the apply button when the value is valid
* Don't add error style to the text field when the value is empty or when it doesn't contain an equal sign

Traverse AdwEntryRow's widget tree to remove visibility of the title labels and change alignment of the text entry to center.

This implementation is tightly coupled with the internal representation of AdwEntryRow. Checks were added to prevent crashing if that representation changes, but in such case the layout may get askew.
