Special GitLab references not rendered in releases

Problem to Solve

Currently, the special GitLab references do not behave the same across Release Notes for a Release created by a Tag and the Release Page.

Example

If you use special gitlab references into release notes of a tag (ie: reference to an issue), this reference provide a link in tags page: perfect.

When you look at the release page (Project -> Releases) => the link does not exists.

#<issue_number>, would be rendered as <current_repo/issues/<issue_number>

Proposal

Match the linking functionality and behavior across the Release Page and Release Notes.

We need to explicitly provide the current user to the markdown_field helper in lib/api/entities.rb

       expose :description
       expose :description_html do |entity|
-        MarkupHelper.markdown_field(entity, :description)
+        MarkupHelper.markdown_field(entity, :description, current_user: options[:current_user])
       end
       expose :created_at
