feat: use dynamic config to supply custom beta feedback banner

[bmuenzenmeyer]

Description

Feedback within nodejs/nodejs.org#8998 (comment) suggested that the beta docs themselves could have a feedback mechanism. To my knowledge, we can do this (once merged to main)

Validation

Upon merge - we should get a custom banner at https://beta.docs.nodejs.org

PR Summary

Low Risk
Build-time config and static banner metadata only; no auth, data, or core doc generation logic changes.

Overview
Adds beta-specific doc-kit configuration so the Vercel build passes --config-file ./beta/doc-kit.config.mjs into generate, wiring the web target to load remote site config from main via remoteConfigUrl.

That remote config is defined in beta/site.json, which sets an index websiteBanners entry (“Give us feedback on the new docs” linking to the doc-kit issues). Banner copy and link can be updated on main without changing the build script, once this is merged and beta deploys use the config.

I'd really like if this preview stuff was all in its own directory, so we can remove it when we are done with it

[avivkeller]

btw are the new diff comments too detailed?

btw are the new diff comments too detailed?

on top of being broken markdown tables, perhaps

edit: otherwise, they are fine. we are used to verbose PR output

[avivkeller]

I'll improve them :-)
