Resolve "Improve the git_data_dirs deprecation message as per documentation"
The two options we had are
- Fix docs to follow the JSON format.
- Fix the code to print hashrocket syntax.
I picked the latter because
- Throughout the gitlab.rb template, we suggest hashrocket syntax.
- Docs were there first, deprecation came later.
Closes #3198 (closed)
