<i18n dev> RFR: 8303833: java.util.LocaleISOData has wrong comments for 'Norwegian Bokmål' and 'Volapük'

[Eirik Bjorsnos]

Please review this comment-only PR which fixes incorrect language names  'Norwegian Bokmål' and 'Volapük' in the comments in LocaleISOData:

`+ "nb" + "nob"  // Norwegian Bokm?l`
`+ "vo" + "vol"  // Volap?k`

These encoding issues seem to have been around since Duke imported the file in 2007. Let's fix them now.

For context: 'Norwegian bokmål'  is the most common written form of the Norwegian language:

'Volapük' is a constructed language:
