Changes needed to localeData.json

[zepumph]

From phetsims/chipper#1332 (comment), @solaolateju and I have found some changes we want to make in the localeData for all sims.

• rh roh Romansh: It should be rm(right) and not rh (wrong).
• nk nor Norwegian: similarly, it should be no (right) and not nk (wrong).
• We also noticed that ar_EG should add a locale3 called arz. That is in the IANA list. I'm not sure about the process for this. It may require a rebuilt of all sims to support it as a query parameter.
• Add a new locale: pr
• Add BCP47 values, from spreadsheet updates in Adjust HTML language attribute chipper#1332

I will coordinate with @jonathanolson to make this happen.

From @solaolateju in phetsims/chipper#1332 (comment)

You are right. There are no sim translations for both affected locales.

This is our first batch of changes to localeData.json since the initial MR over in phetsims/joist#963.

@jonathanolson mentioned the following steps:

• Coordinate with @mattpen because the website uses this file too
• Do a translation deploy so we don't increment the MR.
• Test these changes quickly after deploy to make sure the new localeData.json is behaving correctly (because it will be live immediately).
• Double check with @solaolateju to see if there are any other changes to add.
• Add validation based on IANA list.

IANA list for "validation". @jonathanolson and I discussed perhaps checking this into babel: https://www.iana.org/assignments/language-subtag-registry/language-subtag-registry

@mattpen when you're back, I'll want to coordinate with you on whether this would potentially break anything. Patch to update localeData is in the commit above (on the bcp47 branch in babel).

EDIT: comment deleted, looks like this was already discussed.

I imported the changes into the website, it actually looks like an improvement as Java is now recognizing the new locales and providing localized names. @jonathanolson - we have a production deployment planned next week, I think after that happens this can proceed.

Sounds good! Thanks
