Add mmkv v4 support for MMKV dev tools

[theafolayan]

This pull request updates the @dev-plugins/react-native-mmkv package to support the latest versions of its dependencies and aligns the code with breaking changes in the react-native-mmkv API. The main focus is on upgrading to react-native-mmkv v4 and updating the usage of its API in the codebase.

Dependency upgrades:

• Upgraded react-native-mmkv from ^3.1.0 to ^4.0.0 in package.json, and updated expo to ^54.0.0 to ensure compatibility with the latest ecosystem.
• Bumped the package version from 0.4.0 to 0.4.1 to reflect these changes.

Code changes for react-native-mmkv v4 compatibility:

• Replaced the deprecated MMKV constructor with the new createMMKV factory function in useMMKVDevTools.ts. [1] [2]
• Updated the storage removal method from delete to remove to match the new API in react-native-mmkv v4.
