[docs] [issue35190] collections.abc.Sequence cannot be used to test whether a class provides a particular interface

[Miro Hrončok]

I fail to understand what abc classes can be used to test whether a class provides a particular interface, and what abc classes cannot be used that way. What is the difference between those abc classes and why are all those abc classes listed together when they behave differently?
