Docs feedback: Jira 8.13+ does not work for user namespace

Link the doc and describe what is wrong with it.

IN configuration of Jira DVCS, Step 1 indicates that you should create a user in GitLab that has access to all projects. This is not the case when using Jira 8.13+ and GitLab 13.0+.

The new Jira DVCS request for group API, when adding user namespace it gives group not found error.

In Jira 8.13 and below, you can use personal namespace to access the repository, but Higher version you cannot. Also, adding a user to a project do not give Jira access to the project. So Jira DVCS will not sync the repository unless they are owned by the user.
