Remove jobs.js

[drewbo]

The file at api/jobs.js runs scheduled jobs but there are two issues with this file/pattern:

• We run all other scheduled jobs via our queue workers
• This only runs one job, an audit which removes users from a site using SiteUsers, a deprecated access pattern

Acceptance Criteria

• Remove this file, job, and associated dependencies

Noting, per Chesterton's Fence, that we previously used this job to audit sites, ensuring that people without Github write access were removed from the SiteUsers, a now (semi-)deprecated access pattern. Searching the logs, the job itself has been running daily as scheduled but hasn't removed a user in at least one year.
