Add support for y-axis zoom in renderConfigurableZoomableTrendChart()

[steve-dwyer-itdev]

Add an optional argument (allowYAxisZoom) to renderConfigurableZoomableTrendChart() to enable y-axis zooming via the dataZoom e-charts option.

Testing done

Verified the chart with, and without the allowYAxisZoom set to true. See screenshots below.
Using the y-axis slider correctly zooms the chart.

allowYAxisZoom = false

allowYAxisZoom = true
