Drawing text sample outdated

[2E0PGS]

The following is outdated it now takes PointF instead of IPath.

Samples/ImageSharp/DrawingTextAlongAPath/Program.cs

Line 46 in b776ea0

.DrawText(textGraphicsOptions, text, font, Rgba32.Black, path));

It would look like this now:

PointF pointF = new PointF(60, 170);

image.Mutate(x => x.DrawText("My text here", font, Rgba32.Blue, pointF));
