The wrap parameter for OptionList no longer works

[davep]

Starting in July 2023 (cb819fa ) OptionList has had a parameter to control if options should auto-wrap or not. As of Textual 1.0 it would appear that this parameter is now a no-op. Setting it to False has no effect and, after a brief look at the OptionList code, I can't see the value being actually used any more.

This will also affect SelectionList as it is designed to work as a non-wrapping descendent of OptionList.

This does, of course, potentially break the layout of any application that is relying on an OptionList that truncates rather than wraps its Options.

A quick jog back through the blame history suggests that the regression started around here: 1a5fbb3
