Merge branch 'fix-find-file-links' into 'master'

Fix find file navigation links

## What does this MR do?
Modified the tables in [find file page](https://gitlab.com/ClemMakesApps/gitlab-ce/find_file/master), so that clicking the entire row will go to the file rather than forcing the user to click on the text

## Are there points in the code the reviewer needs to double check?
We should be good

## Why was this MR needed?
Resolve UI inconsistency. Other pages UX indicate that the rows are clickable when highlighted. It is not the case for this page
