* Extend the Options section of the PDF Writer documentation

When I used PHPWord to write a PDF document, recently, I followed the
docs only to find that I also had to specify a PDF renderer — otherwise
the operation failed.

After a bit of research to figure out what to do to specify one, I
thought it only right to document what I learned in the official
documentation.

* Update the docs changelog detailing the PDF Writer additions

This change updates the changelog to include the enhancement made to the
PDF Writer docs that show how to specify a PDF renderer when working
with the PDF writer.

* Fixed docs

Fix PHPOffice#2548. A particularly perplexing problem accidentally introduced by PR PHPOffice#2475. Problem does not arise for Php8, and does not arise for Php7 unit tests. But, running *not* under Phpunit auspices with Php7 can cause a warning message at destructor time if the `save` function has been used. A very artificial test is introduced to test this situation.

* Generate Table Cell if Row Doesn't Have Any

Fix PHPOffice#2505. Word treats file as corrupt if a table row does not contain a cell (documentation for why this is so is included in the issue). Person reporting the issue suggests that dropping such a row from the output file is preferred. However, I think generating an empty cell instead is closer to the user's expectation. For example, as demonstrated in the unit tests added with this PR, if a table has row 1 and 3 which contain cells, but row 2 does not, the table as written to the file will have 3 rows, with the second containing an empty cell.
