fix: Add types to ensure that there will be no compilation errors when struct: false

[duan602728596]

I used the v8 version of react-redux in the project.

When typescript is configured with strict: true, The type of let listeners = [] is recognized as any[].

When typescript is configured with strict: false, The type of let listeners = [] is recognized as never[],
This will cause listeners.push(listener) to prompt the error TS2345: Argument of type 'Listener' is not assignable to parameter of type'never'..

When project is not configured with strict: true, this will cause a project compile-time error, so I added a type here to solve this problem.

Thanks!

Huh. Yeah, the added type for the array is useful here, but I'm also curious how you even ran into this. This is an internal structure that isn't exposed to consumers of the library. Did you have your app configured to try to compile dependencies out of node_modules or something?

Maybe I didn't ignore node_modules, so I ran into this problem.
This is a demo that I can reproduce: https://github.com/duan602728596/react-redux-build-project.
In this demo, the files in node_modules/react-redux/src were checked during compilation and an error was given.
This is the case with my project.

Yeah, I would normally advise against trying to compile or type-check any code in node_modules :)

Yes, I will pay attention to these in the future.
