Summary:
Expand TorchScript `__init__` annotation warning to `list` and `dict` with reference to GSD task T187638414 and annotation warning reproduction D56834720.
Currently, the TorchScript compiler ignores and throws `UserWarning`s for the following annotation types for empty values within the `__init__` function: `List`, `Dict`, `Optional`. However, the compiler should additionally cover warnings for `list` and `dict`. This diff adds support for `list` and `dict`.
Test Plan:
Added 4 new unit tests:
`test_annotated_empty_list_lowercase` and `test_annotated_empty_dict_lowercase` verify that TorchScript throws UserWarnings for the list and dict type annotations on empty values.

`test_annotated_with_jit_empty_list_lowercase` and `test_annotated_with_jit_empty_dict_lowercase` verify that TorchScript throws UserWarnings for the list and dict type annotations on empty values with the jit annotation.

Approved by: https://github.com/davidberard98
Updates flake8 to v6.1.0 and fixes a few lints using sed and some ruff tooling.
- Replace `assert(0)` with `raise AssertionError()`
- Remove extraneous parenthesis i.e.
- `assert(a == b)` -> `assert a == b`
- `if(x > y or y < z):`->`if x > y or y < z:`
- And `return('...')` -> `return '...'`
