As a Jira Admin,
I want to set the value for the Parent Link field using behaviours,
so that I can automatically control the value when a user interacts with the issue.
Users would like to set the `Roadmaps for Jira` Parent Link field using the behaviours `setFormvalue` method.
Ideally, have it take the issue key as the value in the same way you can use the issue key to set Issue Picker fields.
