Release of urllib3 version 2 broke anaconda-client

See https://github.com/Anaconda-Platform/anaconda-client/issues/654. The temporary fix seems to be something like
```
          # release of urllib3 >=2 broke anaconda-client
          conda install -y anaconda-client 'urllib3<2.0.0'
```
I'm currently testing this with the 1.24.4 release.
