Upgrade the mirador-share-plugin to v0.16.0

Is your feature request related to a problem? Please describe. Opening the mirador viewer on a IIIF item, the "copy" button does not trigger any action if you click on it. So it's not clear whether you clicked on it or not.

This issue was fixed in v0.16.0 of the mirador-share-plugin (https://github.com/ProjectMirador/mirador-share-plugin/tree/v0.16.0).

The pull request https://github.com/ProjectMirador/mirador-share-plugin/pull/49 describes our expected behavior:

Click on each "copy" button and see that a notification window is triggered in the top center (it should have a green background, with a success icon and message that says "Link/Code/Manifest copied to clipboard!")
