The Webpack bundling tests fail when we merge a release PR.  The release action and the webpack tests run concurrently, and what happens is as follows:

1. The FLE webpack tests bundle mongodb-client-encryption into a tarball and install it into the webpack application
2. `npm i` is run inside the webpack application
3. prebuild attempts to download a prebuild.  But at this point, the release is in-progress and the prebuilds have not been published to the new Github release, so the install fails.

We likely want to `--build-from-source` or manually build the bindings into the webpack'd application instead of relying on prebuild to download the bindings.
