fix(app): correct removeDataStore return type, add docs for getBundle…

[KushalMeghani1644]

Summary

This PR makes small improvements to the @tauri-apps/api/app module:

• Improved documentation: Added JSDoc for getBundleType (with example and @since tag).
• Type safety: Restored the correct generic for invoke in defaultWindowIcon to ensure proper type inference.
• Consistency: Added example usage for setDockVisibility and clarified DataStoreIdentifier description.

Motivation

These changes improve correctness, developer experience, and consistency across the API surface.
The fixes are non-breaking and align with existing patterns in the codebase.

Checklist

• Corrected removeDataStore return type
• Added missing JSDoc for getBundleType
• Fixed type error in defaultWindowIcon
• Improved consistency in documentation and examples

@lucasfernog It's probably too late, but the package that needs the bump is @tauri-apps/api not @tauri-apps/cli
