docs: capteesys -- Typo in example

[jenisys]

Current example (probably a copy+paste problem):

def test_output(capsys):  # -- PROBLEM HERE, SHOULD BE: capteesys
    print("hello")
    captured = capteesys.readouterr()
    assert captured.out == "hello\n"

CHECKLIST:

• a detailed description of the bug or problem you are having
• minimal example if possible
