[macOS] The default system commands are not translated

[GitGianluc]

Describe the bug
Some system commands (such as closing the application, entering full-screen mode, etc.) are displayed in English even when the application language is set to Spanish or Italian.

Steps to reproduce

1. Launch Tero Subtitler.
2. Click on New empty subtitle on startup.
3. Go to Tero Subtitler > Settings… > General and set Language to Italian - Italy or Spanish - Uruguay.
4. Close the dialogue, then click on the Tero Subtitler toolbar item: under the menu item equivalent to Settings, all commands are displayed in English.
5. Click on the toolbar item equivalent to Edit: under the menu item equivalent to Format Properties…, all commands are displayed in English.
6. Click on the toolbar item equivalent to View: the last command is displayed in English.
7. Click on the toolbar item equivalent to Help: the alternative text shown inside the search bar is always Search.

Expected behaviour
In theory, when a language other than English is set for the application's interface, all commands should be displayed in the chosen language.

Current behaviour
Some remnants of English commands are still displayed even if a different language is set for the application's interface.

Furthermore, all the commands in the new “Colors” dialogue window also remain in English when a different language is selected.
