Fix Beta Features menu items not being translated

• Fixes STU-1248

Proposed Changes

• Convert BETA_FEATURES from a static constant to a factory function (getBetaFeaturesDefinition) that calls __() at runtime. This ensures translations are loaded before the strings are evaluated.

Testing Instructions

• Append this translation at the end of common/translations/studio-es.jed.json

"Multi-Worker Support":["Compatibilidad con multiproceso"],"Enable multi-worker PHP processing for faster performance":["Habilita el procesamiento multiproceso de PHP para obtener un rendimiento más rápido"],"Xdebug Support":["Compatibilidad con Xdebug"],"Enable PHP debugging with Xdebug (one site at a time)":["Habilita la depuración de PHP con Xdebug (solo un sitio a la vez)"]

• Start Studio and switch language to non-English (e.g., Spanish)
• Open Beta Features menu (Studio menu > Beta Features on macOS)
• Verify menu items display in the selected language
• Toggle a beta feature on/off and verify it persists after restart
• Change the language to English
• Confirm the beta features are displayed in English

Pre-merge Checklist

• Have you checked for TypeScript, React or other console errors?

Nice fix! The change looks good and works as expected. The beta features are now translated:

When a beta feature is toggled, the setting persists after app restart.

Thanks @sejas for solving this! I have tested it, and I can see the translation now in the Beta features menu, toggling them also persists after closing and opening Studio. Changes LGTM!
