[docs] [issue29756] Improve documentation for list methods that compare items by equality

[Steven D'Aprano]

Steven D'Aprano added the comment:

To be clear, I'm referring to the docs in the tutorial:

https://docs.python.org/3.7/tutorial/datastructures.html

and the docstrings as well as the library reference:

https://docs.python.org/3.7/library/stdtypes.html#sequence-types-list-tuple-range

The library reference already notes that `remove` uses equality, but the others do not.
