Remove attribute transformation logic when extracting claims from IDToken

[DonOmalVindula]

Purpose

This pull request removes the logic that transformed attribute names (e.g., from snake_case to camelCase) when extracting user claims from the ID Token. Now, the original attribute names from the ID Token payload are preserved in the extracted claims. This affects the core extraction utility and its tests across the JavaScript, Browser, and React packages.

User Claims Extraction Logic:

• The extractUserClaimsFromIdToken function no longer converts claim attribute names to camelCase; it now preserves the original attribute names from the ID Token payload.

Documentation and Test Updates:

• Updated the function documentation and examples in extractUserClaimsFromIdToken.ts to reflect that original attribute names are preserved, not camelCased. [1] [2]
• Revised test cases in extractUserClaimsFromIdToken.test.ts to expect original attribute names (e.g., given_name, phone_number) instead of camelCase versions. [1] [2] [3] [4] [5] [6]

Release Notes:

• Marked as a minor release for @asgardeo/javascript, @asgardeo/browser, and @asgardeo/react with a changeset describing the removal of attribute transformation logic.
