[ASIM] - Change PluginInfo and add some type annotation

[BeneBr]

Add some new property requirement which includes the sdk_version, python_version for plugins and add some type annotations.

Nice cleanup!

However, we should not add "sdk_version" explicitly like this -- SDK is something used by ALFAsim but is not necessarily true for all users of hookman.

We should add a way to add generic requirements, without naming them, for example I can pass {"a": ">=1.2.0", "b": ">=3.0.0"}.

While python_version makes sense, I think it is simpler to just work with a generic requirements: dict[str, str] instead.

For alfasim, we will use hookman passing the requirements explicitly, for example: {"alfasim_sdk": ">=1.0", "python": ">=3.10,<3.11"}.
