Proposal: IntroduceChangesets for automated versioning and Changelog management

Description:

Suggestion to introduce Changesets to manage versioning

Currently, version updates and changelogs are managed manually which are cumbersome, and could potentially lead to human errors. Additionally, it seems like only the version of sdk is updated when there is a change so far. While it might not seem like a critical issue, I believe that when sdk is updated, both the sdk itself and the packages that depend on it need to be updated as well.

With our recent transition to a monorepo structure, these challenges are amplified due to the increased complexity of managing multiple interdependent packages. Implementing Changesets would streamline this process by automating version management and changelog generation across all packages in the monorepo.
