[v3.0.0-next.2] Post Logout Redirect URI proto set incorrectly when behind TLS-terminating reverse proxy

[heikkilamarko]

I've encountered an issue with the post logout redirect URI protocol being set incorrectly when my API is behind a TLS-terminating reverse proxy. Despite configuring the post logout redirect URL with the "https://" protocol, the SDK implementation sets the protocol to "http." This is likely due to the reverse proxy terminating TLS and calling the service without TLS.

	proto := "http"
	if req.TLS != nil {
	proto = "https"
