What happened?

conda-lock doesn't run under python 3.12 as ensureconda crashes.

ensureconda is currently broken under python 3.12 due to using the now removed distutils. This is detailed in https://github.com/conda-incubator/ensureconda/issues/24 and a fix is available in https://github.com/conda-incubator/ensureconda/pull/22 but needs to be merged.

Additional Context

This is especially noticable now that GitHub has updated their runners to use python 3.12 by default.

[jfrost-mo]

Ensureconda has been fixed in version 1.4.4, so this now just requires updating ensureconda.

[maresb]

We should probably also fix #596 here.
