Add Support for Python 3.12 (#1237)

Resolves #1065 


### Description

This adds support for Python 3.12. Once this is merged, the plan is to:

* Increment the version of MF and publish it.
* Update `dbt-metricflow` to use that new version since CI depends on
that package.
* Update CI to add tests for Python 3.12.
