'Unstable' is not shown for neutrons. Do we want this? #163

Closed Luisav1 closed 1 year ago

Not sure if this is a bug or on purpose and if so how come we don't show it? https://github.com/phetsims/build-a-nucleus/blob/9385abf655e86824c8e75436ac37230866165595/js/decay/view/StabilityIndicatorText.ts#L42-L54

The above commit shows stability for when only neutrons are present too. But we want to double-check with @ariel-phet that is behaviour we want.

@ariel-phet and I discussed this, and found https://en.wikipedia.org/wiki/Neutron, with this:

A free neutron is unstable, decaying to a proton

This means that @Luisav1 fixed a bug above, and not just a pedagogical error. Thanks!
