Translation choices/nomenclature

[eld120]

Wasn't paying close enough attention previously to the translation choices nomenclature. Changed to the following:

Native Spelling (localization setting)

# for example if localization is set to 'en'
English 
Nederlands (Dutch)

# for example if localization is set to 'nl'
English (Engels)
Nederlands 

• The localized translation is always in parentheses for translation choices
• The language choice before the parentheses is always written in it's native script and spelling so that native speakers can easily identify their preference

This PR looks like it updates the spec to be what we want it to be!

However, main is broken right now. I updated the spec to match the current situation (in #2512), and merged it.

(so now you'll have to deal with the merge conflict, sorry/not sorry)

Also, there are now some specs that need to be uncommented in spec/requests/locale_detection_request_spec.rb

(from 174e9f2 - other changes to fix main)

I looked at the spec in spec/requests/locale_detection_request_spec.rb and the tests that were commented out seemed to be mistakenly labelled as nb/norwegian where they should have been es/spanish - basing this off of the expected test results. Updated and running tests

[sethherr]

1. Do the tests fully cover nl, nb and es ?
2. It looks like you still have to add the spanish test back in spec/helpers/localization_helper_spec.rb (see here, sorry should have commented it out not deleted)
