Changes to FileColumn allowing mouse click access to multiple files(.md, .png, etc.)

[gabenogu]

…by mouse click.

Describe the changes you have made here: There was an issue when opening files such as .md or .png that were linked to a BibText entry. We made changes to the FileColumn that added an event listener allowing for the click to be registered for different files(I.E. multiple file extensions).
Closes #12005

Thanks, overall looks already good, just some minor code style so far. Need to take a closer look at the functionality and a review from a second maintainer

@Siedlerchr sorry for the premature approval from my end, i assumed checkstyle issues were fixed and only checked openrewrite test on my phone

[Siedlerchr]

All fine! checkstyle was green but there was still the "supress" line
