Ideas for new @remotion/studio APIs

[Jonny Burger]

Will probably separate those into issues, but just dumping what I have in mind

• updateDefaultProps() #3451
• writeStaticFile()
• watchPublicFolder()
• deleteStaticFile()
• saveDefaultProps()
• focusDefaultPropsPath('data', 0, 'type') --> will scroll to this path in default props editor
• duplicateComposition() --> Use existing codemod
• renameComposition() --> Use existing codemod
• deleteComposition() --> Use existing codemod
• Open in editor
