Update the CI workflow for changesets so that releases are triggered manually instead of being automated. This will give maintainers better control over when packages are published and allow for review before release.

Tasks:

• Modify the changesets workflow file to disable or remove auto-publishing steps.
• Add documentation to the repository on how to trigger a manual release (using workflow dispatch, etc).
• Ensure the workflow is still functional for other CI checks and PR validations.

Benefits:

• Prevents accidental releases
• Allows more thorough review before publishing
• Maintainers can coordinate releases with other changes
