refactor: update stale figure_plots docstring cross-references in Examples

Replace all :meth:`~anyplotlib.figure_plots.Plot1D.*` and
:meth:`~anyplotlib.figure_plots.Plot2D.*` Sphinx cross-reference strings
in the Examples directory with the correct new module paths
(anyplotlib.plot1d.Plot1D and anyplotlib.plot2d.Plot2D) following
the project reorganization that deleted figure_plots.py.
