np.unicode aliased to np.compat.long #18287
Description
It appears a bug was introduced in numpy when deprecating type aliases in #18230. The bug caused np.unicode to be aliased to np.compat.long which is an alias for int. This was quick to track down because of a typo in the deprecation message (unciode).
https://github.com/numpy/numpy/blob/v1.20.0/numpy/__init__.py#L209-L212
Reproducing code example:
import numpy as np
np.unicode("hello")Error message:
<stdin>:1: DeprecationWarning: `np.unciode` is a deprecated alias for `np.compat.unciode`. To silence this warning, use `np.compat.unciode` by itself. In the likely event your code does not need to work on Python 2 you can use the builtin `str` for which `np.compat.unciode` is itself an alias. Doing this will not modify any behaviour and is safe. If you specifically wanted the numpy scalar type, use `np.str_` here.
Deprecated in NumPy 1.20; for more details and guidance: https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations
Traceback (most recent call last):

ValueError: invalid literal for int() with base 10: 'hello'
