localeProperty validValues changed

[zepumph]

In some recent change, the localeProperty's validValues changed in some sims removing a few supported locales, and it is failing CT for PhET-iO migration.

ph-scale main is missing zu and sn compared to 1.6 acid-base-solutions main is missing mt and ps compared to 1.3 gravity-and-orbits main is missing zu compared to 1.6

I want to link https://github.com/phetsims/gravity-and-orbits/issues/485 with this issue because both started happening over the weekend-ish and I can't find a cause (yet). Tagging @samreid so he knows too. Here is what a CT error looks like:

Looks like this was a regression caused by https://github.com/phetsims/phet-io-wrappers/commit/ef678f62844b04592bc07caa0488e4f6676d1d65. Sorry!
