Closes #461

Summary

Use array-valued x-extensible-enum and other x-*-enum schema extensions as display enum values. Standard enum remains authoritative when both forms are present, and extensions on array item schemas are handled as well.

Validation

@sb123sb123 Thanks for the contribution, and apologies that we didn't get to this in time. 🙏

We've released Redoc v3.0.0 with major changes, so we're closing PRs opened against the old version. If this is still relevant for v3, feel free to rebase onto main and reopen it, and we'll review it.
