ci: Update 'Remove old wheels' workflow anaconda-client to v1.14.0 (#156)

* Update anaconda-client in the old wheels removal workflow to v1.14.0.
   - Drop python from the environment creation arguments as python is a
     dependency of anaconda-client and the CPython version used should not be
     a concern here, as this is a conda package.
