Thanks for the PR, but this file is auto-generated from Google Closure Library. If you want to fix this, then the way is the following:
If the Closure Library has this wrong, then open an issue there and then ask here for the locale information to be regenerated
If the Closure Library has this right, then
If regenerating the locales fixes this, then send a PD with this
If regenerating the locales does not fix this, then check why this is the case and send a PR with a fix

I am closing this now as this PR is not following the guidelines
