[COP-1752] add getDX tracking to environment startup

[Tofel]

This PR adds getDX tracking for environment startup using solution that has been used in the local CRE for the last 3 months. It uses GH CLI to download API token for CCIP1.7 project. If user doesn't have GH CLI installed (or authenticated) it will store data on the local file system and push it once GH CLI becomes available. setup-gh task was added to the Justfile to ease GH installation.

If tracker fails to initialise a no-op implementation will be used.
