fix(misc): make generated ci workflow work without nx-cloud (#23199)

## Current Behavior
<!-- This is the behavior we have today -->

`ci-workflow` generators error if Nx Cloud has not been enabled.

With the new Github onboarding flow, there is a chicken or the egg
problem.

The Github onboarding flow creates a PR but we don't have a pipeline to
run against it. To create the pipeline, Nx Cloud has to be enabled...
which... creates a lackluster PR.

## Expected Behavior
<!-- This is the behavior we should expect with the changes in this PR
-->

`ci-workflow` generators do not error if Nx Cloud has not been enabled.
This way, the `ci-workflow` generator will be able to create a workflow,
which the PR made by Nx Cloud's Github onboarding flow will be run
against.
