Entry validation | Random Number Generator

The RNG action allows you to set and to save the min and max values such that the max value is less than the min value.

e.g
min: 10

max: 8

Actual behaviour: allows user to quit the configuration, and to save the workflow

Desired behaviour: numbers set in configuration for the action should be validated on save, or on attempting to close configuration, or some other method (eg. using an update button in config)
