Description:
Standardize Python version number placement in init.py

Looks good to me from a code perspective for all these pull requests @aht007 . I assume there is some external reason we chose the solution which places the version in a separate file, and I'm curious what that is. Or simply do more repos place the version in init.py than do not and this is less work?

@connorhaugh Actually We are going to run a cleanup job for semantic release workflow and that workflow will need the current version of the package so we need it to be at some standard place for all repos so that we have a single source where we can look in each repo i.e. the 'init' file. Now for the question about why this approach, I will link a discussion here ARCH-BOM-DISCUSSION
Hope it clears any concerns from your side.
