Template code generation contains a GitHub token

[netomi]

In the file https://github.com/eclipse-opensmartclide/smartclide-smart-assistant/blob/main/smartclide-template-code-generation/smartclide_wizard/config.py#L7 a GitHub token is configured and committed to the repo.

Checking the token revealed that it is not active anymore, but such tokens should never be committed to the repo. Please update the code to not have hard-coded tokens in the config.py file but rather let them be defined by environment variables or config files not checked into the repo.
