Fix the casing of the svg color MediumAquamarine in StatisticalPlots.pl.

[drgrice1]

Although JSXGraph is lenient with this, LaTeX and TikZ are not. So if you use the greens color palette you end up getting the stroke color for this color in TikZ output. but an aqua marine color for JSXGraph output.

Here is a MWE for testing this:

DOCUMENT();

loadMacros('PGstandard.pl', 'PGML.pl', 'StatisticalPlots.pl', 'PGcourse.pl');

$barPlot = StatPlot(xmin => 0, xmax => 7, ymin => 0, ymax => 10);
$barPlot->add_barplot(
    [ 1 .. 6 ],
    [ 3, 6, 7, 8, 4, 1 ],
    fill_colors => { palette_name => 'greens' }
);

BEGIN_PGML
[<
    [<[@ $barPlot->image_type('Tikz'); @]* [!TikZ bar plot!]{$barPlot}{400}>]
    [<[@ $barPlot->image_type('JSXGraph'); @]* [!JSXGraph bar plot!]{$barPlot}{400}>]
>]{ [ class => 'd-flex gap-3 flex-wrap' ] }
END_PGML

ENDDOCUMENT();

I thought I had fixed all of these in my changes to #1374, but I seem to have missed this one.

It seems my editor's format on save also removed some spaces at the ends of lines in the POD that @pstaabp left in there.
