feat(typescript): add private modifier for private methods

[satya164]

When generating documentation for methods in class components using TypeScript, I have some methods marked as private because they are internal and don't want to show them in the docs. But I don't have any information regarding whether a method is public or private in the currently extracted metadata. In this PR, I'm adding a modifier for private methods so I can know which methods to exclude.

Thanks. I was just thinking we probably can do the same for private methods in javascript but what react-docgen is actually doing is documenting the API if a react component, so props and (public) methods. I even think we probably shouldn't even include private methods.
I guess that would work for you too?

It works for me. Should I update the PR to filter out private methods?

Thank you, I made the change to skip private methods. It will be in the next version.
