[Meta] Automatic String Organization (jellyfin#1372)
* Automate String Organization. * Comment the script so it's easier to maintain? Or messier? * Linting post comments * Rename ShellScript -> Alphabetize Strings for tvOS * use swift regex, add error messages, clean up separators * Only search for ./Translations/en.lproj/Localizable.strings * Purge Unused Strings Script * Organize Translation Scripts into a Folder. Update references at the project level. * clean up --------- Co-authored-by: Ethan Pippin <[email protected]>
