Depreciation of @gcornut/valibot-json-schema

[gcornut]

👋 Hello,

I'm here to warn you that @gcornut/valibot-json-schema is now deprecated as Valibot now has an official JSON schema converter 🎉 !

It's not extremely urgent to migrate to @valibot/to-json-schema as my lib will continue to work on Valibot schema as long as no breaking changes are introduced in Valibot.

Some of the features not been ported yet (like bigint and date conversion) because they are controversial (they imply non-standard JSON serialization/deserialization). But please open issues on the Valibot repository if you need them re-implemented.
