type is_dtype_equal

[MarcoGorelli]

• Closes #xxxx (Replace xxxx with the Github issue number)
• Tests added: Please use assert_type() to assert the type of any return value

There's already a test for this one using assert_type;

pandas-stubs/tests/test_api_types.py

Lines 125 to 126 in feebd47

	def test_is_dtype_equal() -> None:
	check(assert_type(api.is_dtype_equal("i4", np.int8), bool), bool)

the function just wasn't typed

In the stubs, we don't include type definitions for methods that are not documented. In this case, is_dtype_equal() is not documented, so I'd prefer to just delete the line from the stubs.

On the other hand, if you think it should be documented, then you can raise an issue in the pandas repo, and we make a decision about this PR after the doc issue is resolved.

sure thing, always happy to delete code

[Dr-Irv]

We have references to is_dtype_equal() in pandas-stubs\api\types\__init__.pyi and pandas-stubs\core\dtypes\api.pyi that should be removed as well.

UGH. Now that I see that this is used in a test (this one is copied from the pandas source), I think we need to open an issue in pandas about documenting this. I'll do that, and keep this PR on hold.
