Update Smoke Tests to Reflect Default Behavior After Feature Flag Removal

[kbukum1]

Summary of Changes

This PR updates the smoke tests to align with the behavior after the removal of the enable_fix_for_pnpm_no_change_error feature flag.

Although the feature flag had been enabled for the past two weeks, the smoke tests were still running without it. Now that the feature flag has been removed, the previously gated logic is the default behavior, and the smoke tests are now executing this code for the first time. As a result, adjustments were required to adapt the smoke tests to the new expected outputs.

Why This Change?

• The enable_fix_for_pnpm_no_change_error feature flag was removed from dependabot-core and dependabot-api, making its logic the new default.
• Smoke tests were not previously running with this flag enabled, meaning they are now interacting with this code for the first time.
• Updates were needed to ensure that the test expectations reflect the new behavior.

Key Updates

• Modified test expectations to match the now-default behavior that was previously behind the feature flag.
• Verified that all test cases align with the latest Dependabot behavior without requiring feature flag conditionals.

Validation & Testing

• Smoke tests now pass with the updated expectations.
• Confirmed that the changes align with the behavior enforced by the recent feature flag removal.
• No unintended test failures or discrepancies in recorded outputs.
