rangeSlider: sliderOptions not properly propagated to ionRangeSlider

[zopyx]

See

Pretty mode is enabled and the prettify() function is supposed to return 'foo' for each value - however the slider still shows the related numbers.

Please take a look at src/fields/optional/fieldRangeSlider.vue

The documentation for the range slider appears to be entirely incorrect. The correct schema property is rangeSliderOptions
