Correct documentation on ModbusServer::poll()

[SimonFJ20]

The ModbusServer::poll()1 function returns an int, in the docs it said it returned nothing (void). I have changed the API-documetation to match the actual function declaration and doc-comment.

I observed this on the Arduino website.2 I have archived the Reference page with the mistake on Wayback Machine for future reference.3

I don't know if i have made the change in the correct file, but the mistake was the same in it, so I assume it supplies the information for the website.

In case my assumption is true: may i ask why the documentation on the website isn't auto-generated from the doc-comments in the code files?

Would it be too much to also add to this ticket a little more explanation on the poll() method such as whether it is blocking?

More documentation would always be better, but at least this is a small fix and the OP seems to have not reacted on your feedback. I'll go ahead and merge this but I'll be happy accepting further pull requests with more detailed documentation enhancements.
