Checklist

• Used a personal fork of the feedstock to propose changes
• Bumped the build number (if the version is unchanged)
• Reset the build number to 0 (if the version changed)
• Re-rendered with the latest conda-smithy (Use the phrase @conda-forge-admin, please rerender in a comment in this PR for automated rerendering)
• Ensured the license file is being packaged.

Notes

• revert add noop legacy output for nteract-scrapbook #6
• fix pip check failing for nteract-scrapbook #7

At some time in the future, we might be able to figure out a usable approach to this kind of renaming, but for now not worth the hassle.

Next steps:

• admin-request to mark noarch/nteract-scrapbook-0.5.0-pyh44b312d_1.tar.bz2 broken
