feat: add type hinting for the JwtHelperService.decodeToken method

[patricio-ezequiel-hondagneu-roig]

Changes

Updated the decodeToken method in the class JwtHelperService to accept a generic type argument that will be used as the type of the returned value, defaulting to any to preserve the current behavior when no type argument is used and avoid a breaking change.

With the change the user can hint the type of the value returned by the decodeToken method instead of having to resort to a type assertion.

Example of usage without a type hint:
