Remove hot-updater/babel-plugin from babel config (gone in 0.32.0)

0.32.0 no longer exports ./babel-plugin (the package now only exports
the config entry), which broke the build with ERR_PACKAGE_PATH_NOT_EXPORTED.
The plugin's only job was replacing the __HOT_UPDATER_BUNDLE_ID build-time
constant; the 0.32.0 client reads the bundle ID from the native module
(getBundleId()) instead, so no babel plugin is required.
