/**
 * Transform package.json in @firebase/database so that we can use scripts/exp/release.ts to release Database exp.
 * It does following things:
 * 1. Update package.json to point to exp binaries
 * 2. Update version to '0.0.900', the version number we choose for releasing exp packages
 *    (9 stands for v9, 900 to avoid conflict with official versions).
 *    The release script will append commit hash to it and release the package with that version.
 *    e.g. 0.0.900-exp.fe85035e1
 * 3. Replace peerDependencies with the exp version, so the release script can match and update them to the correct version.
