Update telemetry connection strings (#692)

## Changes
This PR updates the connection string for Application Insights for the
telemetry collection of the extension.

## Tests
- [x] When using the Run Extension launch configuration without change,
telemetry is uploaded to our development Application Insights instance.
- [x] Manually removed the `EXTENSION_DEVELOPMENT` environment variable
from the Run Extension launch configuration and verified that the new
telemetry was uploaded to our production Application Insights instance.
