Update go-chi/session (fixes "race" in tests) (#17031)

Update to latest go-chi/session where the NewManager causes a new
Provider instantiation instead of reconfiguring an old one.
(https://gitea.com/go-chi/session/pulls/1)

The NewManager call is now concurrency safe and would allow live
reconfiguration in future but for now this PR simply fixes an
intermittent "data-race" detected in our tests.  (See
