chore(nx): bust build cache on babel config change (redwoodjs#6443)

nx uses caching to determine which steps to do/not do when running something like yarn build

Out of the box it does it's best to determine which changes correctly trigger a rebuild, however it doesn't really account for config files such as a babel config.

Changes to the babel config file, need to bust the build cache as they can have a huge effect on the built artifacts given we use babel to build our JS. This PR ensures that changes to the babel config, correctly allow for a rebuild of the framework.
