[unbound-method]: don't report unbound methods passed to jest.mocked

[FloEdelmann]

import foo from './foo'

jest.mock('./foo')

jest.mocked(foo.bar).mockResolvedValue(baz)
//          ^^^^^^^ jest/unbound-method reports an error here

expect(foo.bar).toHaveBeenCalled() // no error here

Since jest.mocked will be called with mock functions, it should not make a difference whether it is bound or not, right? So I'd suggest to not report an error for unbound methods passed to jest.mocked, just like already happens when passing it to expect.
