Update grpcio and pip package versions

The current grpcio version 1.51.1 fails to build on aarch64 based MacOS
computers. Update the version of the grpcio and grpcio-tools packages to
the latest 1.57.0 version. There are binary wheels available for this
version from PyPi for aarch64 MacOS.

Also update the pip version for the Conda environment. It seems a newer
version of pip is required to detect and install these wheels.

Testing:

invoke test passes and I can start the bumble-pandora-server
successfully.
