Provide production-ready memory store for eypress-session (#5212)

Browse source 
The `express-session` library comes with a session storage meant for
testing by default. That is why you get a message like this when you
start up LibreChat with OIDC enabled:

    Warning: connect.session() MemoryStore is not
    designed for a production environment, as it will leak
    memory, and will not scale past a single process.

LibreChat can already use Redis as a session storage, although Redis support
is still marked as experimental. It also makes the set-up more complex, since
you will need to configure and run yet another service.

This pull request provides a simple alternative by using a in-memory session
store marked as a production-ready alternative by the guys from
`express-session`¹. You can still configure Redis, but this provides a simple,
good default for everyone else.
