[GIT-ACTIONS] Automate parts of the release process

[PaulGregoryBaker]

Goal:

As a mojaloop maintainer
I want to make the process of making Mojaloop releases easier by using automation where possible
so that I can facilitate the access of new features as soon as the development is completed, to the adopters.

Note: This story is about automating parts of the release process so that releases are quicker to make, reducing the overhead involved and making maintenance easier.

Acceptance Criteria:

• Verify that a github actions script for release automation is created
• Verify that the application versions part of the release is automated
• Verify that the script creates helm release candidate branch
• Verify that the script update chart versions
• Verify that the script deploys and tests the release candidate branch to Moja2
• Verify that package versions can be overridden in scenarios where the latest version is not to be used in a release Tracked in [GIT-ACTIONS] Implement package version override in Helm release workflow #3738
