Fix #14319 Add parse float for steps less than 1

[kadencewp]

Description

I added a check to see if the step property is set to less then 1. If so to change the newNumericValue variable to use parseFloat.

on line 51 changed this:

const newNumericValue = parseInt( newValue, 10 );

to this:

let newNumericValue = parseInt( newValue, 10 );
if ( props.step !== undefined && props.step < 1 ) {
	newNumericValue = parseFloat( newValue );
}

How has this been tested?

Checked with all core blocks, as well as all Kadence Blocks :)

This should be dropped for #14322

This was only a way to make things work, 14322 is a real step forward.
