Refactoring package.json for Better Compatibility and Efficiency

[pplancq]

Hello,

This pull request includes several changes to the package.json file to improve the library's compatibility and efficiency:

1. Move from jest to peerDependencies: This change allows users of this library to use their own version of Jest, increasing compatibility with different projects.

2. Move from @types/jest to optionalPeerDependencies: Similar to the above, this allows consumers to optionally use their own TypeScript typings for Jest.

3. Type libraries moved to devDependencies: This prevents these libraries from being installed by consumers of this library, thus reducing unnecessary installations.

These changes are intended to make this library more efficient and compatible with a wider range of projects.

Please review these changes and provide your feedback.

Best.

Thanks! Some of these ideas I've considered in the past, and I'll have a look at this tonight.
