Link to Doc: Project Access Token

Customer wishes to disable Project Access Token feature on GitLab. (Internal link)
The steps are not shown on the documentation. They need to click on Version history and click on "Became enabled by default in GitLab 13.3." to know what is the feature flag name to disable.

Can we add the feature flag name in the document? Or add a section on how to disable this feature?

Steps to disable Project Access Token feature flag on the instance level through Rails console:

sudo gitlab-rails c
Feature.disable(:resource_access_token)
