Remove nanoc excludes
Remove nanoc excludes for the internal link test which were causing broken masters whenever links were broken in in the excluded directories.
Proven (I think) in gitlab!25970 (closed), as a broken link in each directory was not caught by the internal link test.
Pointed out in gitlab#207429 (comment 292562642), for a broken master.
Another broken master example: gitlab#208118 (closed)
Closes gitlab#207429 (closed)
Closes gitlab!25970 (closed)
