Infrastrcuture as Code Type? (Required)

terraform

Use Case (Required)

As a user of the accelerator, I want to use an alternative auth method than PAT for the accelerator bootstrap, e.g. gh cli or the standard env vars.

Proposed Solution (Required)

Remove the input variable for the primary PAT as it is no longer required to be passed anywhere. Update the docs to show users how to auth with cli / env var instead.

Important Factoids (Optional)

This was no possible in an older version, but is now due to requiring a specific lesser scoped PAT for agents / runners.
