Add Github workflow to automate changelog and release pages

[parthosa]

Fixes #369

The release process within GitHub is automated using a GitHub Actions workflow script.

GitHub Release Workflow:

File - .github/workflow/release.yml

This workflow is triggered when a branch prefixed with 'v*' is pushed. The following steps are executed:

1. Checkout Code
2. Create Change Log using a third-party library.
3. Prepend Current Change Log to CHANGELOG.md in the main branch.
   • Commit and push changes to the main branch.
4. Create a Release using the output obtained from step 2.

File - .github/workflow/configuration.json

A configuration file to customize the output of change logs.

Library Used - https://github.com/marketplace/actions/release-changelog-builder

Thanks Partho!
It will be nice to update the user_tools README file to have a link to the CHANGELOG in the main branch. This is similar to what we have for the user-guide link.

Great Job @parthosa !

I am fine with PR.

One final issue that @mattahrens can reflect on:
For the upcoming release the changes will be added at the top of an empty changelog. Are you ok with that?
Or do you want to manually pre-populate the changelogs with some of the most recent releases?

It's fine to populate on top of an empty changelog. If needed, we can go back and add in later.
