Merged

Adds a section to install.md describing the new cross-platform install flags. Notes the Node.js-compatible value set, the default-to-current behavior when only one flag is provided, and the conflict with --global. Refs denoland/deno#32785

There was a problem hiding this comment.
This matches denoland/deno#32785: --os/--arch are local install flags, accept Node-compatible process.platform/process.arch values, and conflict with --global. No check-runs are reported for this 2.8-branch PR, so holding approval until CI is green.

Resolves conflict with --package-json subsection (PR 3075) added on 2.8; keep both new subsections side by side under deno install.
