When mocking with `unsafe=True` the mocked instances don't receive the unsafe argument.

Bug report

When the feature Check against misspellings of assert etc. in mock was introduced, the unsafe flag was moved out from kwargs and defined as a named argument.
Previously since unsafe was implicitly part of kwargs, it was silently propagated from _patch class to the instantiation of the klass variable inside the __enter__ method.
But now, the unsafe flag as an explicitly named argument is not being propagated to the instantiation of the Klass variable.
Hence the Mock class is unable to set its internal attribute _mock_unsafe and will always be False regardless of whether the user set unsafe=True or not.

The test cases have to be updated to show this bug.

This bug was introduced in this commit: fdb9efce6ac211f973088eef508740c3fa2bd182 (bpo-41877) and only included in versions from Python 3.10.

Your environment

• CPython versions tested on: 3.10, 3.11 and master branch.
• Operating system and architecture: Ubuntu 22.04

Comece pela classe _patch e pelo seu método enter, onde a instância de Klass é criada, e inspecione como unsafe é passado para Mock. Atualize os casos de teste relevantes para demonstrar que unsafe=True chega às instâncias mockadas e que o estado interno unsafe delas muda de acordo.
