CPS-464: Add Github Action to Automate Release Pull Request Creation

[deb1990]

Overview

Added https://github.com/compucorp/release-pr-action Github Action to Automate Release Pull Request Creation.

Before

The pull request had to be manually created, and the changelog also needed to be manually created by checking difference between last tag and master branch.

After

Now all of this is automated using Github Actions.

Technical Details

Added compucorp/release-pr-action@1.0 action.
Also the jira_ticket_number and version_tobe_released input is taken from user, which is then passed to the action

VERSION_NAME: "${{ github.event.inputs.version_to_be_released }}"
FILE_UPDATE_COMMIT_DESC: "${{ github.event.inputs.jira_ticket_number }}: Update info.xml"
RELEASE_PR_TITLE: "${{ github.event.inputs.jira_ticket_number }}: Release v${{ github.event.inputs.version_to_be_released }}"
