Currently the collection `.save()` command errors with a `MongoshInvalidInputError` error. As this command has been removed in the driver as of 4.0 we should be able to drop it entirely. Currently we are printing a message with the error that states the command is deprecated. If we don't remove it we should at least update the message to be explicit that the command has been removed.

Driver 4.0 Changes where `.save()` was removed:

Where we updated to the node driver 4.0 and removed the .save() support (in collection.ts): https://github.com/mongodb-js/mongosh/pull/451/files#diff-c975be9c4e061c8d6cf6aac2dd4da42c6096bdf5e8e62601eca89f85e22302c3R760
