React v2.1.1

[JakeLo123]

What is this PR and why do we need it?

This is to handle #82. This also Adds onAutoRefreshFailure callback as a config option to react via the core package. (Let's add this to Vue ASAP to help #13 and resolve this same issue, which is likely occurring there).

Testing
To make this easier/faster, I would log into FA admin dashboard and set the JWT expiration time to 60 seconds and test from there. Your refresh call should happen after 50 seconds.

Testing the success case

• Log in and await the refresh call. You should remain logged in longer than 1 minute.

Testing the failure case
You can create a refresh failure by configuring the SDK like so:

{
  shouldAutoRefresh: true,
  tokenRefreshPath: "/app/something-fake",
  onAutoRefreshFailure: (e) => console.error("Refresh failure!", e),
}

You should be automatically logged out 10 seconds after the refresh failure.

Other Changes

• Bump react SDK version to v2.1.1 and regenerate docs
• Add yalc scripts to publish/push react sdk to package json
• Remove CookieHelpers class wrapper because it’s not needed.
• Remove CookieHelpers, UrlHelper, and TokenRefresher classes from package public API.
• Add onAutoRefreshFailure to SDKConfig
• Remove TokenExpirationScheduler and TokenRefresher and re-implement via the core
  • I’m starting to feel that these abstractions they make the core class slightly harder to understand rather than the opposite. I think that un-abstracting them is a good decision.

Pre-Merge Checklist (if applicable)

• Unit and Feature tests have been added/updated for logic changes, or there is a justifiable reason for not doing so.
