Safely bump to next valid version

https://appwrite.io/docs/advanced/self-hosting/production/updates

> **A note about migration**
>
> You can migrate to versions that require a migration path and are higher than your current version, such as from 1.5.0 to 1.5.11.
>
> If you're trying to migrate to a next major version such as from 1.5.0 to 1.6.0, you will first need to migrate to the latest patch version 1.5.11, then to 1.6.0.
>
> It is highly recommended to [back up your server](https://appwrite.io/docs/advanced/self-hosting/production/backups) data before running the migration. It is recommended to run the migration process on a dev instance and make sure your application is working well and that you have checked for any breaking changes in the new version [changelog](https://github.com/appwrite/appwrite/tags).

appwrite-tooling should enforce those requirements.
