Datestrings from moment not correctly localized

[raimund-schluessler]

The dates that moment.js parses are not correctly localized anymore. This happens since the migration to vite as a bundler in #2321.

nextcloud/moment should normally load the correct localization on its own, which it did when the app was still build with webpack.

Since we switched to vite, the bundled moment version always uses the english locale. Weirdly, when executing moment in the javascript console, the correct locale is used (but that might be the global moment from server).

@susnux Do you have any idea what could go wrong with vite that the locale does not work anymore?

This seems to be related to tree shaking because the locales are not imported for moment thus they are removed. Fixed this on the nextcloud-moment package. See nextcloud-libraries/nextcloud-moment#781
