Mark auth-helpers packages as deprecated on npm

[hmnd]

The Auth helpers package is in maintenance mode and we won’t be actively improving it

Now that the Auth helpers packages are no longer recommended, I'd like to suggest officially marking the packages as deprecated on npm, in order to warn existing users of these packages.

It's also confusing that this repo is called auth-helpers, even though the main supported package is ssr.

please do not do this. SSR is still full of issues and updating would break every app I have built

@oldbettie marking as deprecated would not prevent you from using it; it would just indicate to users that it is no longer maintained.
