[Breaking change] Parameter was renamed on OpenIdConnectHandler.HandleSignOutAsync

[javiercn]

V1:
protected override async Task HandleSignOutAsync(SignOutContext signout)
V2:
protected override async Task HandleSignOutAsync(SignOutContext context)

https://github.com/aspnet/Security/blob/dev/src/Microsoft.AspNetCore.Authentication.OpenIdConnect/OpenIdConnectHandler.cs#L153

It breaks on classes overriding the method and calling base with named arguments

Eh, let's fix the breaking change. The old parameter name wasn't awful.
