build, doc: move to redesign

[avivkeller]

This is not ready for merge, nor is it ready for a detailed review

This is here for @nodejs/web-infra to experiment on integrating this redesign into core.

Ideally, not much should need to change besides these values, but alas, we do not live in an ideal world, and something will probably break.

Moving out of draft to test CI.

Pull request overview

Updates Node.js doc build configuration to experiment with the redesigned documentation output by switching doc-kit templates away from the legacy “all-in-one HTML” generation.

Changes:

• Switch doc-kit HTML generation template from legacy-html-all to web (Makefile + Windows build).
• Stop declaring out/doc/api/all.html as a required/produced doc artifact in the doc-only Makefile target.

Reviewed changes

Copilot reviewed 2 out of 2 changed files in this pull request and generated 2 comments.

File	Description
Makefile	Uses the web doc-kit template and removes all.html from declared doc build outputs.
vcbuild.bat	Uses the web doc-kit template during Windows doc generation.

Comments suppressed due to low confidence (1)

Makefile:838

• The comment above this doc generation rule still says it generates all.html/all.json, but all.html is no longer a target/output in this rule. Please update the comment to match the new set of generated artifacts to avoid confusion for future maintainers.

# Generate all doc files (individual and all.html/all.json) in a single doc-kit call
# Using grouped targets (&:) so Make knows one command produces all outputs
