Add storybook parameters

Feature description

In my storybook, I have globals like light and dark theme. I'd like to be able to run tests on both of these modes.

import type { CustomProjectConfig } from 'lost-pixel'

export const config: CustomProjectConfig = {
  storybookShots: {
    storybookUrl: './storybook-static',
    globals: {
       color: ['light', 'dark'],
       brands: ['acme', 'diffbrand']
    }
  },
  generateOnly: true,
}

Ideally these would run tests with the query param: &globals=color:dark;brand:acme but with an enumeration of each type. It'd be really cool if we could tie into psuedo parameters to say this story will run for acme and diffbrand, but the rest only run for a single brand.
