feat(workflow): add GitHub Actions workflow for publishing @flowiseai/agentflow

- Introduced a new workflow to handle version bumps and publishing of the @flowiseai/agentflow package.
- Supports various version bump types (prerelease, patch, minor, major, custom) and allows for custom version input.
- Includes a dry-run step to validate the version and simulate the publish process before actual deployment.
- Configured to use pnpm for dependency management and publishing tasks.
