fix: Remove Tensorflow embeddings node (no-changelog) (#7922)

## Summary
This PR removes `embeddingsTensorFlow` node and reverts our fix to
accommodate the Docker build in #7893 .
The node itself has been extracted as a [community node available from
npm](https://www.npmjs.com/package/n8n-nodes-tensorflow)
