Feature Request/Idea: Make the popover preview image size configurable

[summitcheung]

Overview of the Feature Request
The default value for the popover preview of thumbnail image under the "Files" tab on the dataset page is 400, as shown in the below element:

div class="popover-content"
img src="/api/access/datafile/3?imageThumb=400"

It would be great if it can be made configurable to that users can preview larger image and see more details before downloading it.

What kind of user is the feature intended for?
Guest

What inspired the request?
Upon users' request.

What existing behavior do you want changed?

When mouse hovers over a thumbnail, users can preview larger image, for example doubling the current default size to a value of 800.

Any brand-new behavior do you want to add to Dataverse?
No
Any open or closed issues related to this feature request?
