Work Items: Auto expanded summary quick view using markdown

Summary

In #15694 (closed), GitLab introduced the ability to auto-expand a GitLab issue url into its title by appending + to the end of the url. For example https://gitlab.com/gitlab-org/gitlab/-/issues/15694+ becomes Render the title of a referenced issue within m... (#15694 - closed).

As a boring MVC to deliver a summary of OKR status, we want to take this concept further and append additional metadata to the title for a "quick view" of the record. This will be helpful when sharing updates of a project and/or OKRs.

Proposal

Introduce +s (signifying "summary") as a new suffix which once appended to the end of a url will auto-expand the record into title_assignee_milestone_health status. This feature should be available for work items and issuables.
