Relocate 'Create Issue' button on Vulnerabilities Details page

Problem

There's currently a way to create a new issue from a vulnerability in the dashboard, in an effort to enhance this functionality by allowing 'related' issues (in addition to creating issues) we need to work toward a UI that is more extensible & in-line with the UX described in #9424 (closed).

Proposed solution

As an iterative step toward the UX described in #9424 (closed) we will relocate the "Create Issue" button & update the display of the issue created to match the "Related issues" UI element displayed here:

Design:

Changes

• Add related issues section to vulnerability page
  • Move create issue button into related issues section header
• Add system notes for issue creation in the vulnerability page

At the moment there is no reference on the issue page itself of the associated vulnerability. This presents a few challenges, the biggest being the exposure of a vulnerability in a public issue or an issue that should not contain this sensitive information. I think we hold off on that until we have more clarity on the workflow.

What success looks like

Look & feel of "Create Issue" button, link to created issue, and system notes are in-line with the UX described in #9424 (closed) to set up the page for the additional enhancements described in that issue.

Technical Implementation

• Move the button inside RelatedIssues component (which still needs to be created at the time of writing)
• Update old tests and write new tests
• Update documentation
