Hi @ramijebara
I have updated dependencies to Angular 15 by using -

1. https://update.angular.io/?l=2&v=14.0-15.0
2. cexbrayat/angular-cli-diff@14.2.0...15.1.4
   Please do the needful further review. This is my first time to contribute so kindly Let me know if I am missing any workflow here.

Thank you,

Looks good so far, Thank you!
I have added a couple of comments and suggestions for you. Please take a look and update the PR as needed.

@pavandixit93 Thank you! I noticed you made some changes in response to the comments. Please give me a chance to review and let you know.

@pavandixit93 I will accept and merge your PR. Thank you. Please note that after the PR is merged I will make some minor changes to remove code and config that is no longer relevant. Once done, I will push the new package to npm.
