Built in badge for releases

Problem to solve

Gitlab only offers 2 badges: pipeline and code coverage. Theres a lot more to a project then those two aspects, and there should be more badges to reflect that. The first I suggest is a Latest Release badge

Intended users

Proposal

Opening a merge request to create the badge. Will follow the same pattern as the pipeline badge and coverage

for example: https://img.shields.io/badge/Latest%20Release-v10.3.4-blue

The 2 fields required for badges is "Image url" and "Link". The image url will look like https://gitlab.com/%{project_path}/badges/release.svg and link will be https://gitlab.com/%{project_path}/releases

Permissions and Security

The badge should work for private repos as well as public. This is the reason gitlab should provide these badges: so that granting access to external badge generators isn't required.

Testing

What does success look like, and how can we measure that?

What is the type of buyer?

We have added a new badge so you can easily see your latest release.
