Additional Localizations in macOS File Provider

[i2h3]

This is a follow up pull request to #8507 which was already merged by accident.

[i2h3]

I am still working on the enablement of relevant localizations within the Xcode project so localizations arriving from Transifex in the strings catalog actually are considered. It will be ready and pushed on some minutes.

Pull Request Overview

This PR adds additional localization support to the macOS File Provider by extending language support and making accessibility descriptions localizable. The changes focus on improving internationalization for users of the Nextcloud desktop client's macOS shell integration.

• Added support for over 100 additional language codes in the Xcode project configuration
• Updated hardcoded accessibility descriptions to use localized strings for better i18n support
• Converted share type descriptions from hardcoded English text to localizable strings
