Ability to pass micromatch options when configuring story loading

[brandonferrua]

Is your feature request related to a problem? Please describe
I have a need to parse out documentation stories within a monorepo. Due to our monorepo structure, matching the glob pattern is adding complexity to parse the stories I want to showcase in our documentation. Per https://storybook.js.org/docs/react/configure/overview#configure-story-loading it does not seem possible to pass in micromatch options into the configuration, even though it's using micromatch to parse the files behind the scenes.

Describe the solution you'd like
The ability to pass in an object with micromatch options to the stories key.

module.exports = {
  stories: {['../src/**/*.stories.@(js|mdx)'], options},
}

Describe alternatives you've considered
I can get the paths of all story files and then build my own filtered array using #11181 (comment). Though it seems like I'm just recreating this feature request at that point?

Are you able to assist to bring the feature to reality?
no

what options do you want to provide?

We currently have a need for the ignore option to be passed into micromatch. Could it just accept an object with any of the micromatch options? Would be happy with just ignore though.

By chance I was looking at this today and from what I can tell micromatch is only used to generate a regex that is used in a require.context. I don't think passing micromatch options would work unless the options are specific to the makeRe function (the makeRe function doesn't have the ignore option).

I could be wrong but the only reference I found to micromatch is this one, so that's what I based this observation on.
