Describe the bug
It's difficult to copy an artifact link (rather than downloading / opening it) from the task UI.

To Reproduce

Steps to reproduce the behavior:

1. Open a task in the UI, e.g: https://firefox-ci-tc.services.mozilla.com/tasks/HkcTlRWqSwGV9x1Oy9lOfQ#artifacts
2. Try to copy the artifact link
3. The only way to do so is to right click and use the browser's context menu (e.g "Copy Link Address" in Firefox).
4. This URL includes the bewit parameter which means if you send it to someone else, they won't be able to open it
5. So you first need to paste the URL into somewhere editable and manually remove the query parameter

Expected behavior

Copying the artifact URL should be easy.

Additional Context

In Releng we often just want to link people to the artifact. E.g, linking to the signed build in the task above.
