make validation parameter in cypress helper function as a function

[Yokozuna59]

I think we need deeper validation; using imgSnapshotTest isn't enough some times, e.g., configure styles (#4527) or diagrams (#4263).
 
I'm suggesting making the parameter an object; the first parameter is a helper function, and the second is options passed to it. Since each diagram has its own attributes, maybe create a helper function with some .shoulds and expects that verifies the passed arguments are as expected. For example:
 

// cypress/helpers/pie.ts
export const pieHelper: CypressHelperFunc = (svg, options: PieAttributes) => {
   if (options.width !== undefined) {
     expect(svg).to.have.attr('width', options.width);
   }
   ...
}

 
We could add their helper method at the top of each spec file, or maybe add it to cypress/helpers with the name of the spec itself.
