Feature Request: version metadata `message` property

Hi :wave:,

The workers logpush dataset contains a new `scriptVersion` object with three properties: `id`, `message` and `tag` (ref: https://developers.cloudflare.com/workers/configuration/versions-and-deployments/gradual-deployments/#logpush).

The binding however only contains `id` and `tag`. Is that an intentional choice, or could we get `message` added to it as well?
Ref https://workers-types.pages.dev/#WorkerVersionMetadata from https://github.com/cloudflare/workerd/blob/789638f0ef63e485ec03cfee13672cce10abff11/types/defines/versions.d.ts#L5-L10

In my testing, it appears that message is indeed missing from the binding: https://version-metadata-binding.danifoldi.workers.dev/, so it's not just a missing type declaration
