[EN] Finding the alternate solution of sign-in with google.

[RudrasSingh]

Description

-The task was to look for some other options instead of the Sign in with Google which come from google as a button directly including a lot of tracking, So the potential option Authlib with Google is used in solving the problem by completely removing the Google's initial button. [issue 34] (https://github.com/smlab-niser/tirtha-public/issues/34).

Changes Made

• Created a new google authentication flow using authlib with django and made the changes in the views.py.
• Created a button in index.html file including its CSS in style.css.
• Removed the function in the .js file which was handling the sign in workflow previously.

Related Changes

• Included a user profile image in the button once the user signs in.

Checklist

• [x] Code follows the style guidelines of the project.
• [x] All tests pass locally.
• [x] Documentation is updated
