Ability to add classes to icon__wrapper

Patch attached.

Better patch.

I have review this issue. I see the classes are getting added to the svg icon wrapper.
Below example phrase will add a class to its wrapper.

{{ icon('fa-2x fa-solid fa-shake', 'Icon title', ['extra-class', 'another-class'], {'name-one': 'value-one', 'name-two': 'value-two'}, {'wrapper-classone' : 'wrapper-classvalue'}) }}
Attaching screenshot for reference.

Thanks @mitthukumawat - we need to update the main page with an explanation how to add these wrapper classes, I saw them as moreso being:

{{ icon('fa-2x fa-solid fa-shake', 'Icon title', ['extra-class', 'another-class'], {'name-one': 'value-one', 'name-two': 'value-two'}, ['wrapper-class-1', 'wrapper-class-2'] }}
