Subject: [PATCH] fix: Correct multiple author display (#856)

## Summary

* If an EPUB has:
```
<dc:creator>J.R.R. Tolkien</dc:creator>
<dc:creator>Christopher Tolkien</dc:creator>
```
the current result for epub.author would provide : "J.R.R.
TolkienChristopher Tolkien" (no separator!)
* The fix will seperate multiple authors: "J.R.R. Tolkien, Christopher
Tolkien"

## Additional Context

* Simple fix in ContentOpfParser - I am not seeing any dependence on the
wrong concatenated result.
