New release needed

[nicoonoclaste]

I just noticed that there's been no new release cut since early 2023.

While the only functional change since then seems to be #47, it still means users are not getting warned of the deprecation (at least if they use a software distribution which uses the releases tagged here)

After a long wait, we just released 1.1.0! https://pypi.org/project/mypy-extensions/1.1.0/
