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.

I will coordinate with @jonathanolson to make this happen.

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.
