Update export syntax in victory index

[becca-bailey]

I noticed that we also have a large default export in victory/index. Updating this to the ESM export syntax shouldn't change the imports.

The existing export was a named export list export { ONE, TWO, ... } it wasn't a export default { ONE, TWO, ... }, so it can stay as-is if we want. But this change is fine if we want to just do re-exports at the point of import. I'm cool with whatever you and @boygirl want!

Oh, okay! I missed that. This was a two second change, so we can close it if it doesn't make a difference!

@beccanelson Let's merge this because it's nicer. I don't think we need to make a patch just for this change though.
