Fix float values

[diegotibi]

Adds step="any" to input type when type is number to prevent a bug that occurs when number is used for non integer values.

Example:
Let's have an API that support Latitude and Longitude as input values
/*
* @QueryParam lat number Latitudine. Example: 45.3267105
* @QueryParam lng number Longitudine. Example: 7.995482
*/
The generated documentation example will have a field that look like this:

<input type="number" style="display: block;" name="lat" data-endpoint="GETapi-v2-carrier-eolo-secondary-check" value="45.3267105" data-component="query">

As per validation rules the browser won't let you indroduce any value that isn't an integer number, so if you need to enter a precise value for testing it will be impossible.
Adding 'step="any"' makes possible to input any numeric value, integer or float.
