Fix setuptools-scm configuration
This MR fixes up the setuptools-scm configuration. This was previously muddled between using SCM and having a hardcoded version in __init__.py.
Maintenance will be performed on git.ligo.org, containers.ligo.org, and docs.ligo.org on Tuesday 9 July 2024 starting at approximately 9:30am PDT. It is expected to take around two hours and there will be several periods of downtime throughout the maintenance. Please address any comments, concerns, or questions to the helpdesk.
