* Assignment: Decorator Function Astronauts
* Complexity: easy
* Lines of code: 3 lines
* Time: 8 min

English:
    1. Modify decorator `check_astronauts`
    2. To answer if person is an astronaut check field:
       a. `is_astronaut` in `crew: list[dict]`
    3. Decorator will call function, only if all crew members are astronauts
    4. If any member is not an astronaut raise `PermissionError` and print
       his first name and last name
    5. Run doctests - all must succeed

Polish:
    1. Zmodufikuj dekorator `check_astronauts`
    2. Aby odpowiedzieć czy osoba jest astronautą sprawdź pole:
       a. `is_astronaut` in `crew: list[dict]`
    3. Dekorator wywoła funkcję, tylko gdy wszyscy załoganci są astronautami
    4. Jeżeli, jakikolwiek członek nie jest astronautą, podnieś wyjątek
       `PermissionError` i wypisz jego imię i nazwisko
    5. Uruchom doctesty - wszystkie muszą się powieść

Tests:
    >>> import sys; sys.tracebacklimit = 0
    >>> from inspect import isfunction

    >>> assert isfunction(check_astronauts), \
    'Create check_astronauts() function'

    >>> assert isfunction(check_astronauts(lambda: ...)), \
    'check_astronauts() should take function as an argument'

    >>> @check_astronauts
    ... def launch(crew):
    ...     crew = ', '.join(astro['name'] for astro in crew)
    ...     return f'Launching: {crew}'

    >>> launch(CREW_PRIMARY)
    'Launching: Pan Twardowski, Mark Watney, Melissa Lewis'

    >>> launch(CREW_BACKUP)
    Traceback (most recent call last):
    PermissionError: Alex Vogel is not an astronaut
