Remove previous job definitions from Code Quality documentation
Problem to solve
There are a lot of examples in the Code Quality documentation of job definitions that we would like to deprecate and do not want people to use.
Proposal
We should remove all but the most preferred method for implementing code quality from the documentation.
Who can address the issue
A backend engineer from grouptesting who is knowledgeable about the best way to use the Code Quality feature in GitLab. Anyone else with a good handle on the Code Quality Feature in GitLab.
