template documentation duplication and errors
Summary
https://gitlab.com/help/customization/issue_and_merge_request_template.md exists and is incorrect.
Steps to reproduce
I am trying to setup issue templates. I googled for "gitlab issue templates" and found the aforementionned page. It says to "go to your project's Settings and fill in the Description template text area under the Issues feature." This is nowhere to be found in 8.12.6 fa20b51c.
Expected behavior
I should have found documentation on how to configure issue templates from the repository, most likely https://gitlab.com/help/user/project/description_templates.md.
Actual behavior
I find outdated documentation that doesn't work.
Possible fixes
It is unclear to me why /help/customization/issue_and_merge_request_template.md
even exists. I cannot find it in the git repository, nor within its history.
My guess is that it was removed and the online history doesn't show it. I would recommend recreating the file and say that feature is deprecated, pointing to the file-based documentation.
