Preview Plugin: dealing with long file names

**Description**
In case some long filenames are found in the distribution of an KG resource, the Preview plugin rendering is challenges. See capture below with CamelSnake on steroid type of filename:

**Acceptance criteria**
- rendering of the plugin should stay inline with others irrespectively of table content
- There should be a way to see the complete filename

**Solution proposal**
To be further discussed in grooming.
- put a file length limit beyond which we put elipsis and show full filename on mouse over.
- wrap filename on multiple lines

Start by locating the Preview plugin's table-rendering entry point and reproduce the layout with the long filename shown in the issue. Compare the plugin's rendering with adjacent plugins, then implement a way to keep the layout inline while still exposing the complete filename. Done means long filenames no longer disrupt the table and the full name remains viewable.
