chore: Add script for copying build output to package dist directories

This will be useful for publishing via Changesets. We can remove this once we've reconfigured Rollup accordingly.

@mcansh Any clue why we'd suddenly be running out of memory in CI? I don't feel like anything has substantially changed about the build other than including the Rollup TS plugin, and I have no such issues w/ Node's default memory limit running locally.

nothing's jumping out at me, but i can take a look

the new build does use almost 3GB of memory though, where as the old one used less than 1GB, so it might be related

however according to https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners#supported-runners-and-hardware-resources they should have 7GB of memory, but im not sure how much of that is actually usable

Builds looked ok to me locally. Think it's worth publishing an experimental from here and actually npm installing a few things to make sure it all looks good?

@brophdawg11 Successfully tested with npx create-remix@0.0.0-experimental-c5bb5cb31. If you want to spin it up you'll need to force install to deal w/ peer deps (need to fix that in the version script), but should be good to go.
