Update nouislider options for image cropper.

Previous slider min and max values caused home and end keys to behave
incorrectly. Min is now 0 to reflect 0% zoom and max is now 100 to
reflect max zoom. Additionally, adjusted step to 0.01 to avoid slow
adjustments when using arrow keys or page up / page down keys.

Issue: #15578
