Add an easy way to copy a resource identifier in web interface

### Proposed change
To give an example, I'm currently trying to move files in this folder from one dandiset to another: https://dandiarchive.org/dandiset/001769/draft/files?location=sourcedata/raw/sub-I71/micr&page=1

To do this using the CLI I need to copy the resource identifier of the files. On the website, there is no obvious way to do this. It would be nice if there was an easy way to copy the resource identifier of a file on the website.

### Alternative options

### Who would use this feature?
Anyone who needs the resource identifier of a file.
