* master: (sentry_sdk/scope.py) remove improper uses of @_attr_setter, (tests/test_basics.py) remove unneeded test_scope_leaks_cleaned_up()

* master: (tests/test_basics.py) add test for push_scope as decorator, (sentry_sdk/_compat.py) satisfy linters

* global-scope-setters: keep global scope setters and remove push_scope() 'as a decorator' code

* global-scope-setters: (api.py) change 'current_scope' property to 'scope'
