docs: Update code_quality.md

Closes gitlab-ce#51676

See merge request gitlab-org/gitlab-ee!8612

Currently, if a job does not have only/except policies, the policy is considered as an unspecified state, and therefore the job is executed regardless of how it's executed and which branch/tags are targetted.
Ideally, this should be specified as only: ['branches', 'tags'], as it indicates that unspecified policy jobs are meant to run on any git references.

It appears that for some jobs
(https://gitlab.com/gitlab-org/gitlab-ce/-/jobs/129705025 for example)
we process a range of commits far greater than necessary, which can lead
to commits getting reverted that were merged a long time ago.
