Disable chromadb telemetry

[Andrew]

https://docs.trychroma.com/telemetry

Added this line to start.sh:
export ANONYMIZED_TELEMETRY=False

I tried using Chroma's Settings() object to set it, but it wasn't letting me specify the db path, so used this method instead.

I think this is working - following their docs. So closing this.
