Ignore Override Warning

| IGNR  | Override (phtml/js/html) | vendor/ampersand/upgrade-patch-helper-test-module/src/theme/Magento_Checkout/web/js/ignore.js                                      | app/design/frontend/Ampersand/theme/Magento_Checkout/web/js/ignore.js                                                              |

In this case vendor/ampersand/upgrade-patch-helper-test-module/src/theme/Magento_Checkout/web/js/ignore.js was updated with some whitespace/comment/etc so its not really changed, so don't bother reporting on it. The IGNR entries are suppressed without --show-ignore

Redundant override

| WARN  | Redundant Override       | vendor/ampersand/upgrade-patch-helper-test-module/src/theme/Magento_Checkout/web/js/redundant.js                                   | app/design/frontend/Ampersand/theme/Magento_Checkout/web/js/redundant.js                                                           |

In this case vendor/ampersand/upgrade-patch-helper-test-module/src/theme/Magento_Checkout/web/js/redundant.js has been updated and is now equivalent (excluding some whitespace/comments) to app/design/frontend/Ampersand/theme/Magento_Checkout/web/js/redundant.js

The app/design override is now redundant and not necessary

Additional test case changes

The additional test cases needed updated as this file is being ignored, due to the fact its only a comment / whitespace from magento/magento2@1697149

Previously a human would have had to look at the change and work it out themselves, now its not reported.

And these files are being flagged as redundant, because vendor/paypal/module-braintree-core/view/base/web/js/form-builder.js has been edited/changed and is now the same as vendor/paypal/module-braintree-core/view/frontend/web/js/form-builder.js
