Porting over Devin's auto snapshots work

[lesliecodes]

Renamed anthology to be consistent with the current naming.
Added a test so we can see it working

Not sure why it's complaining about ChildNode which already comes with Typescript...

packages/story-utils/src/generateSnapshot.ts:13:16 - error TS2304: Cannot find name 'ChildNode'.

13   ) => Promise<ChildNode | null> | ChildNode | null;

LGTM 🤘

Not necessary now (especially since this is a port from Along), but at some point we should skip disabled tests, so that test runs display how many were skipped.

const testFn = story.parameters?.snapshot?.disabled ? test.skip : test;

testFn(`${storyName} is cool`, () => {
  // ...
});

We used to do something similar in axe-storybook-testing: https://github.com/chanzuckerberg/axe-storybook-testing/blob/894e39a5bf4f96c791d5aefa486d9ff568002ec6/src/Suite.ts#L31

@ahuth @dcwither fixed up some things. Can you look over it one last time? Thanks!

Thanks @ahuth! Could you publish 🙏

[ahuth]

Will do, @lesliecodes! I'm going to make another change today, and then will publish. (Unless you need it on NPM ASAP)

[lesliecodes]

Nope, it can wait. :) Thanks!
