[mlir][python] Update minimal version of pybind11 to 2.10. (#117314)

This PR updates the minimal required version of pybind11 from 2.9.0 to
2.10.0. New new version is almost 2.5 years old, which is half a year
less than the previous version. This change is necessary to support the
changes introduced in #115307, which does not compile with pybind11
v.2.9.
