Throw error if GRAPHQL_JWT_AUTH_SECRET_KEY has not been added to wp-config.php

[joshuaiz]

Currently, if GRAPHQL_JWT_AUTH_SECRET_KEY is not set in wp-config.php it causes an internal server error with WPGraphQL and prevents the schema from loading.

Failing to add the key in wp-config.php should present an error in the admin and probably not disable the schema.

Of note: there's also the filter graphql_jwt_auth_secret_key. I propose the plugin, by default, should use a filter that returns the constant SECURE_AUTH_KEY. Would be as secure as the WordPress install itself and would allow the plugin to "work out of the box" while still allowing for custom keys set in functions and wp-config.

I've experienced the same issue. It does not seem right that installing a plugin would result in PHP errors that break a WP site (mine is live).
