Maintenance: Add workflow to update changelog in GitHub and documentation

[phipag]

Summary

Similar to other repositories such as https://github.com/aws-powertools/powertools-lambda-typescript we should include a GitHub workflow that automatically updates the CHANGELOG.md on GitHub and also the documentation on each version release.

Why is this needed?

Currently, the changelog is not kept up-to-date impacting the customer experience!

Which area does this relate to?

Automation

Solution

We should investigate using this GH action: https://github.com/aws-powertools/actions/tree/main/.github/actions/version-n-changelog

Acknowledgment

• This request meets Powertools for AWS Lambda (Java) Tenets
• Should this be considered in other Powertools for AWS Lambda languages? i.e. Python, TypeScript

@phipag I’m interested in contributing to this project. Could you please assign it to me?

Hey @nikkhilaaryan, I think for this one it is better for a maintainer to pickup due to the permissions required for GitHub actions and a quicker testing feedback loop due to this fact. I assigned this issue to myself to reflect that.

I would like to encourage you to checkout any issues marked with good-first-issue issue label that is not yet assigned: https://github.com/aws-powertools/powertools-lambda-java/issues?q=is%3Aissue%20state%3Aopen%20label%3Agood-first-issue

Let me know if you have any questions.
