Design: Display anchor to auto-created merge requests on project vulnerability list

• Main issue: #216027 (closed)

Problem

Context: In #36500 (closed) introduces the auto creation of merge request. The initial design used an alert to display when merge request are created. Displaying an alert was intended to be a temporary solution as an MVC to introduce the feature.

User need: to be aware of when auto-created merge request have been created and are ready for review.

Solution

With the upcoming addition of #208298 (closed), which will display when pipeline is failing. This section could also communicate when there are auto-created merge request created. This also follows the patter of displaying anchor displays MR list w/ pre-filtered label GitLab-auto-fix.

Revisions

• Add display Auto-fix: <#> merge request ready for review. Leveraging pattern seen in #208298 (closed).
• Display a feature introduction banner - Similar to the object page role out, it informs users that the feature is available and links to documentation.
• auto-created merge request label be GitLab-auto-fix instead of GitLab-suggested-solutions (so not to get confused w/ "suggestions" in MR)
