[what-the-diff]

• In the App.tsx file, we changed "Free" to a translated string
• We added translations for default and free_to_use apps in AvailabilityTab.tsx
• Added translation for event name placeholder in EventAdvancedTab
• Changed title from Title to title (lowercase) in EventSetupTab
• Updated navigation info text with new key: default schedule name instead of Working Hours
• Added a new translation for the "copy_public_page_link" key in de, en and es.
• Updated translations of some keys to be more consistent across languages: unavailable -> not available; meeting with user -> Meeting with {{attendeeName}} (added attendee name as variable)
• Fixed typo in German translation ("Unverfügbar" instead of "Nicht verfügbar")
• Changed English text from 'Meeting' to 'Appointment'. This is also reflected on the public page where it says Appointments now instead of Meetings before this change was made
• Update the meta title and description for webhooks page
• Add translation key to enterprise license required component
• Fix typo in Vietnamese locale file (meeting_with_user)
• Change meeting with user string from {ATTENDEE} to {{attendeeName}} so that it can be translated properly on booking form
• Changed the name of some pages in KBar.tsx
• Added translations for those names and sections in SettingsLayout.tsx
