Introduce support for the @oneOf GraphQL Directive about wp-graphql HOT 2 OPEN

Not that there's anything necessarily wrong about dropping support for all EOL PHP versions

@justlevine based on the opt-in telemetry data we track, we have very few active installs on PHP versions older than 7.4. . .but the majority of active installs are on 7.4, so we'd definitely probably not want to go straight to GraphQL v16.

We should maybe consider a formal policy on PHP version support and devising ways to encourage folks that need to update to do so. Possibly some sort of "GraphQL Health Check" of sorts or something along those lines 🤷🏻‍♂️

If we update to latest GraphQL-PHP in order to take advantage of newer features like this, we would likely need to formally drop support of older versions of PHP as GraphQL-PHP supports php formally supports PHP 7.4+ and WPGraphQL currently supports PHP 7.1+.

Keep in mind that this assumes that @oneOf gets merged into GraphQL-PHP 15.x, as v16 will drop PHP 7.4 support.

Not that there's anything necessarily wrong about dropping support for all EOL PHP versions, but if we don't want to be beholden to an upstream dependency's release cycle, maybe there's a way to register the (not-really-a) directive in our plugin.
