Easy driver stepper suport pin labels can be improved

[JaimeLeon2]

Is your feature request related to a problem? Please describe.
In the stepper motor device config for the Easy Driver option, pins are designated pin 1 and pin 2. That is very cryptic and it is anyone's guess which pin is what.

Describe the solution you'd like
Change label of the pins to clearly show which one is "Step" and which one is "Dir".

Describe alternatives you've considered
Maybe a clarification of what is what in a description field?

Additional context
If you don't know, then it is trial and error.
