replace money_format function-call

[Flyingmana]

the class \Varien_Filter_Money makes use of the deprecated money_format function.

this should get replaced with NumberFormatter::formatCurrency()

seems to me this class is obsolete i can't find any usage of it.

@Flyingmana this is not used and a candidate to remove ... isnt it? (#374)

[seansan]

Is this something we can merge? and use NumberFormatter::formatCurrency()

To my understanding the 20.0.x releases are for php 7.4+?

@Flyingmana

I've searched all modules from "ModuleFostering" and no one makes use of it. It's a "good first issue" ... just remove it. (There are a few modules that directly use money_format(), so removing it should not harm)

Edit: shouldn't it pop up in syntax check?
