Can you test the GitHub and LinkedIn new payload way to login for leetcode? For leetcode-cn the api had changed so much, maybe need some time

@zry656565 Could you take a look at this PR? I do not have the knowledge how leetcode auth with linkedin.

@jdneo To be honest, I am not very sure about it too. 😂

@zry656565 I think its just use LinkedIn session to login, you can test the old one (which is down) and the new one for linking your leetcode.com account with LinkedIn. Thanks.
