Resolve "Sort the language list"

What does this MR do?

List the languages in a logical order for the users. Sort the language list alphabetically, by the English name for the language. As no sort is applied to the source data of the list when showing in the UI, it is sufficient to just sort the list.

In order for this sort to make a logical sense to the user, the English name for each language will need to be added to the list, in addition to the native name.
