### Bug description:
Use of this was recently added in Python 3.13 but it is only available in macOS 10.13.4+ and there is not a proper runtime check for availability.

python/cpython | python__cpython-123801 | # `secrets.randbits` returns only nonnegative integers
# Documentation
The docstring of `secrets.randbits` reads, in its entirety, "Return an int with *k* random bits." In fact, it only generates nonnegative integers, like its sister function `random.getrandbits`.
