What

Part of #1343

• Split the manual_release workflow into multiple jobs
  • This is done so that the publish-wheels, publish-web-demo, and publish-crates workflows can run in parallel. publish-crates will end up being quite slow, most likely at least 30 minutes.
• Add publish-crates which runs scripts/ci/crates.py release
  • It assumes that whatever the current version numbers are is what we want to release. If the versions were not updated, publish-crates will not attempt to publish anything.

Note that there's no real way to test this other than doing a release.
