Improve Airlock Notifier Emails

[TonyWildish-BH]

Describe the bug
Airlock import request emails contain a link to the request, but nothing else. The reviewer needs to poke around to find out which project it's for, who requested it, and what they want it for. Without context, it can be difficult to make the right decision. E.g., the same data may be safe to approve for one project, but not for another.

At the very least, the email should contain the workspace name and the name of the person requesting it, so the reviewer can directly contact them if they have a question about the request.

Steps to reproduce

Azure TRE release version (e.g. v0.14.0 or main):

Hi, @TonyWildish-BH you should be able to modify the workflow file within the Airlock Notifier with a custom email template.
Also, I've reclassified the issue as a 'feature' rather than a 'bug' as I don't believe functionality is broken.
