RFR: JDK-8258655: remove <-- NewPage --> comment from generated pages

Fri Dec 18 01:22:02 UTC 2020

Small change to remove an unnecessary comment from the beginning of generated files.  I'm guessing the comment dates from way back when the doc pages were used to generate paper books.  For those that want to identify that point in the file, either the DOCTYPE or start of the HTML elements t should be enough.

No test: it's somewhat silly to rigorously test that the comment will always be missing.
