[Documentation] PAT auth flow is deprecated in 16.4
In 16.4, GitLab will the deprecate old authentication flow for self-managed code suggestions. This means that customers will no longer have the ability to enter a personal access token field in their self-managed instance admins ( #422037 (closed)).
To ensure uninterrupted access to code suggestions, customers must update their instances to use the new authentication flow in 16.3 (a required upgrade stop) / prior to updating to 16.4.
