*Authors*

remove dist files from main branch after release
*cdn*
- clone cdn repo, copy files, and commit/push

*build*
- implement reproducible builds and verify release builds
* uses the last modified date for the latest commit
* See https://reproducible-builds.org/
- the verify workflow also ensures all files were
properly published to the CDN and npm
*docs*
- the new release workflow is documented at build/release/README.md
*misc*
- now that we don't need the jquery-release script and
now that we no longer need to build on Node 10, we can
use ESM in all files in the build folder
- move dist wrappers to "wrappers" folders for easy removal
of all built files
- limit certain workflows to the main repo (not forks)
- version in package.json has been set to beta.1 so that
the next release will be beta.2
- release-it added the `preReleaseBase` option and we
now always set it to `1` in the npm script. This is
a noop for stable releases.
