How to commit & push Magento's vendor directory file in Magento Cloud?

Question

I have made changes in,

Magento/vendor/magento/module-checkout/Model/PaymentInformationManagement.php

I have made changes in above file, But how can I commit these changes and PUSH it to Magento cloud as it will not show in git diff.

Any idea how to push changes of vendor DIR files on Magento Cloud ?

Note : I don't want to override in my app directory as it is bug and I want fix it in direct file.

Changing file(s) in vendor directly is not a best practice. It's better if you create a patch for the changes, and apply the patch in your Magento Cloud.
