Add support for Heroicons v2.0.0 or other icons via SVG

[wamesro]

A new version of heroicons 2.0.0 has been released https://heroicons.com/
are you planning to add this package support for item menu?

or it would be better to add your own SVG that could be copied either from Heroicons or e.g. https://icons.getbootstrap.com/

Released with Laravel Nova 5.0.0
