Guidance on using `clone` command in dbt Cloud

### Contributions

- [X] I have read the contribution docs, and understand what's expected of me.

### Link to the page on docs.getdbt.com requiring updates

At minimum:
- https://docs.getdbt.com/reference/commands/clone
- https://docs.getdbt.com/docs/deploy/slim-ci-jobs

### What part(s) of the page would you like to see updated?

I would want to use `dbt clone` in Cloud to:
- create a "full" schema in development or CI, instead of deferring
- (potentially) manage blue/green deploys (staging → production), on data platforms that support zero-copy cloning

In order to do that, I would create a job (CI / ad hoc) that defers to a job in my production environment.
