Regenerate remote_pb2.py with protoc 3.19.0

Execute "protoc --proto_path=. --python_out=. remote.proto" which
regenerates remote_pb2.py to fix the following error

```
TypeError: Descriptors cannot not be created directly.
If this call came from a _pb2.py file, your generated code is out of
date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible
workarounds are:
 1. Downgrade the protobuf package to 3.20.x or lower.
 2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use
    pure-Python parsing and will be much slower).

unable to load app 0 (mountpoint='') (callable not found or import
error)
