Mypy shows type errors when using has_item, expecting Matcher[Never] #264

Hi, thanks so much for this awesome library! I'm using python 3.10.15, with PyHamcrest 2.1.0 and mypy 1.15.0.

I've tried the following:

from hamcrest import has_entry, has_item

has_item(has_entry("name", "Sky"))

and mypy complains:

error: Argument 1 to "has_item" has incompatible type "Matcher[Mapping[str, str]]"; expected "Matcher[Never]"  [arg-type]

Am I doing something wrong? Is this an issue with mypy? Or is this an issue in PyHamcrest's typing? Or maybe I'm just using incompatible versions of the three?

Thanks for the help!

# More realistic example:
x = [{"name": "Tim", "age": 5},{"name": "Alice", "age": 2},{"name": "Sky", "age": 13},{"name": "Xin", "age": 22}]
assert_that(x, has_item(has_entry("name", "Alice")))

# Cannot infer type argument 1 of "assert_that" Mypy misc
# Argument 1 to "has_item" has incompatible type "Matcher[Mapping[str, str]]"; expected "Matcher[Never]" Mypy arg-type
