We need to upgrade pyzmq to support Python 3.12:

 The following packages are incompatible
  ├─ python 3.12**  is installable with the potential options
  │  ├─ python 3.12.0 would require
  │  │  └─ python_abi 3.12.* *_cp312, which can be installed;
  │  ├─ python 3.12.0rc3 would require
  │  │  └─ _python_rc  , which does not exist (perhaps a missing channel);
  │  └─ python 3.12.0 conflicts with any installable versions previously reported;
  └─ pyzmq 24.0.1**  is uninstallable because there are no viable options
     ├─ pyzmq 24.0.1 would require
     │  └─ python_abi 3.10.* *_cp310, which conflicts with any installable versions previously reported;
     ├─ pyzmq 24.0.1 would require
     │  └─ python_abi 3.11.* *_cp311, which conflicts with any installable versions previously reported;
     ├─ pyzmq 24.0.1 would require
     │  └─ python_abi 3.7.* *_cp37m, which conflicts with any installable versions previously reported;
     ├─ pyzmq 24.0.1 would require
     │  └─ python_abi 3.8 *_pypy38_pp73, which conflicts with any installable versions previously reported;
     ├─ pyzmq 24.0.1 would require
     │  └─ python_abi 3.8.* *_cp38, which conflicts with any installable versions previously reported;
     ├─ pyzmq 24.0.1 would require
     │  └─ python_abi 3.9 *_pypy39_pp73, which conflicts with any installable versions previously reported;
     └─ pyzmq 24.0.1 would require
        └─ python_abi 3.9.* *_cp39, which conflicts with any installable versions previously reported.

The following package could not be installed
└─ coveralls 3.3.1**  is installable and it requires
   └─ coverage >=4.1,<7.0  with the potential options
      ├─ coverage [4.1|4.2|...|5.0.4] would require
      │  └─ python [2.7* |>=2.7,<2.8.0a0 ], which can be installed;
      ├─ coverage [4.1|4.2|4.3.1|4.4.2] would require
      │  └─ python 3.4* , which can be installed;
      ├─ coverage [4.1|4.2|...|4.5.1] would require
      │  └─ python [3.5* |>=3.5,<3.6.0a0 ], which can be installed;
      ├─ coverage [4.2|4.3.1|...|4.5.1] would require
      │  └─ python 3.6* , which can be installed;
      ├─ coverage [4.5.1|4.5.2|...|6.0] would require
      │  └─ python >=3.6,<3.7.0a0 , which can be installed;
