Doc comment ref page claims it will appear in an exported index.html

[jeremydouglass]

Issue description

The "doc comment" reference page says:

Explanatory notes embedded within the code and written to the "index.html" file created when the code is exported.

However, PDE > File > Export Application does not appear to generate an index.html with JavaDoc contents.

URL(s) of affected page(s)

https://processing.org/reference/doccomment.html

Proposed fix

If this is a regression then we should fix JavaDoc generation in the main Processing code base. However if this was a dropped feature, we should either cut that reference text or change it to make clear that this does not work with the PDE export.

Heh, that dates back to applet export. It should just be removed.
