Integrate version bumping into CI pipeline

[Kavignon]

Description

Enhance the CI pipeline to support semantic versioning updates as part of the deployment process. The CI should accept input for the version type (patch, minor, or major) and update the VERSION file accordingly.

Tasks

• Configure the CI pipeline to:
  • Accept a version_type input (patch, minor, or major).
  • Run the mix version.bump task using the specified version type.
• Ensure the updated VERSION file is committed and pushed back to the repository.
• Document the workflow for maintainers in the README.
