Symengine package fails to build in 10.2rc2

[Marc Culler]

The symengine package has apparently not been updated to be compatible with cython 3.

This is what I see in the log (full log attached):

  performance hint: /private/var/tmp/sage-10.2-current/local/var/lib/sage/venv-python3.11.1/var/tmp/sage/build/symengine_py-0.10.0/src/symengine/lib/symengine_wrapper.pyx:4992:5: Exception check on '_ctypes_callback_lambda_real' will always require the GIL to be acquired.
  Possible solutions:
        1. Declare the function as 'noexcept' if you control the definition and you're sure you don't want the function to raise exceptions.
        2. Use an 'int' return type on the function to allow an error code to be returned.

I see your unanswered message "ping" on issue #456 from 5 days ago.

But in the Releases section I see that v0.11.0 was released 2 days ago.

It's not on PyPI yet, as Isuru tells me there.
