tests(binary): error when git email auto-detection is disabled

[ee7]

Description

With 6691484, a configlet developer may see this error when running the integration tests locally:

[Suite] generate
Author identity unknown

*** Please tell me who you are.

Run

  git config --global user.email "you@example.com"
  git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

fatal: no email was given and auto-detection is disabled

Possible solution

Move this logic from the workflow to the test file, and make it run conditionally:

configlet/.github/workflows/tests.yml
