ansible-test - Avoid use of deprecated type hints. (#78456)

* ansible-test - Avoid use of deprecated type hints.

PEP 585 deprecated many container types in the `typing` module in favor of the actual types, which support subscripting as of Python 3.9.

Conversion of `t.Type` was skipped since PyCharm does not currently recognize it.

* ansible-test - Fix `t` and `c` imports/shadowing.
