Update Angular Version in 1-auth-finished Branch

[bhuvaneshsaha]

I've noticed a discrepancy in the Angular versions across branches in the repository. Initially, the main branch 1-start with the latest version (Angular 17), which poses no issues for me as I continue with the course using Node 20 on my laptop until Section 6.

However, upon reaching Section 6, I encounter the need to switch to the 1-auth-finished branch to continue with the course. Unfortunately, this branch utilizes an older Angular version, which prevents me from installing the required dependencies due to compatibility issues with Node 20. It feels somewhat disruptive to have to change Node versions for just one section.

Could we please update the 1-auth-finished branch to utilize the latest Angular version? This adjustment would greatly streamline the learning process and ensure consistency across the course materials.

Thank you for your attention to this matter.
