Release Pipeline

[robin-schoch]

This PR adds two workflows for automatic release of the sgr specification library and the SGrPython library.

Here's a revised version of the PR description:

This PR enables the maintainer to trigger the workflow in two ways: manually with a specific tag name from the specification repository, or automatically via a dedicated trigger pipeline within the specification repository itself.

The sgr specification library workflow can be manually initiated to build and release a Python package on PyPI, which includes the generated Python output. Additionally, this workflow updates the version numbers in both the requirements.txt and setup.py files. Following these updates, it automatically creates a pull request to merge these changes into the main branch.

The second workflow runs for each tag matching this regex v*. This will release the SGrPython library with the provided semantic version in the tag name.

TODOs:

• [x] Add pypi token to the action secrets
• [x] Update the sgrspecification repository setup.py
• [x] Update the import paths for all sgrspecifcation package
• [x] Add new sgrspecification to requriements
• [x] Update the setup.py for SGrPython
• [ ] Optional: Add trigger pipeline to sgr spec

This will close issue #28 #25

@Zupeuc Feedback would be appreciated and please add a pypi token to github action secrets.

@Zupeuc we need the a pypi token to run these github action. I do not have access to sgr pypi organisation. Is it possible for you to add this token to the github action secrets?
