`getUserIdentities` returns incorrect GitHubOAuth string

[TylerJang27]

Calling workos.userManagement.getUserIdentities() can return an identity including:

{ "idpId": "########", "type": "OAuth", "provider": "GithubOAuth" },

The Typescript type is "AppleOAuth" | "GoogleOAuth" | "GitHubOAuth" | "MicrosoftOAuth" (note the case difference).

Subsequently, calling workos.userManagement.getAuthorizationUrl with the returned provider then fails, because it is expecting a GitHubOAuth provider.
