IBX-8502: Added unsupported locale fallback

[reithor]

🎫 Issue	IBX-8502

Issue seems to come from the fact that Intl does not support 3 letter region subtags:
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl

A locale identifier is a string that consists of:
# A language subtag with 2–3 or 5–8 letters
# A script subtag with 4 letters Optional
# A region subtag with either 2 letters or 3 digits Optional (!)
# One or more variant subtags (all of which must be unique), each with either 5–8 alphanumerals or a digit followed by 3 alphanumerals Optional
# One or more BCP 47 extension sequences Optional
# A private-use extension sequence Optional

PR adds a fallback to eng-GB for locales not supported by Intl.

Notes:

• I searched for other occurrencies of Intl.Locale in our code - found nothing
• I also searched for meta[name="LanguageCode"], found some places but only base-ckeditor.js is applying Intl.Locale

@reithor any progress on that?

@dew326 - missed message from @GrabowskiM , will take care of that now.

[reithor]

@dew326 this needs also approval from one maintainer ? @alongosz or @konradoboza ?

[dew326]

I'm the maintainer of this package as well. We are good. You can pass it to QA.
