Add support for manual trigger with --force-regenerate flag in update-models workflow

- Introduced an optional `forceRegenerate` input to the `workflow_dispatch` event.
- Updated the `Update Together.ai models` step to conditionally include the `--force-regenerate` flag based on the input.
- Enables manual triggering of the workflow with enhanced flexibility for regenerating models.
