crypto/tls: run SkipNewSessionTicket bogo test

This commit removes SkipNewSessionTicket from the bogo_config.json
excluded tests list.

Previously this test was being skipped with a TODO that there might be
a bug here. In practice it seems like there's no bug and the test is
handled correctly by crypto/tls.

When activated, a TLS 1.2 client connecting to the bogo dispatcher goes
through the normal handshake process with the exception that the server
skips sending the NewSessionTicket msg expected by the client in
response to the client's final flight of handshake msgs.

The crypto/tls TLS 1.2 client_handshake.go logic correctly rejects the
unexpected message that follows (ChangeCipherSpec) when trying to read
the bytes necessary to unmarshal the expected NewSessionTicket message
that was omitted.

Updates #72006
