Update deploy-jobs.md for self-deferral

The CI Phase 2 beta will now include the ability for Deploy jobs to self-defer. This will be useful for jobs running compile, source_freshness:fresher, and other commands that need to defer to the last successful state of that particular job.

Feel free to suggest other language as well, this is not perfect.

     Older versions of dbt Cloud only allow you to defer to a specific job instead of an environment. Deferral to a job compares state against the project code that was run in the deferred job's last successful run. While deferral to an environment is more efficient as dbt Cloud will compare against the project representation (which is stored in the `manifest.json`) of the last successful deploy job run that executed in the deferred environment. By considering _all_ deploy jobs that run in the deferred environment, dbt Cloud will get a more accurate, latest project representation state.
