PR Summary

Low Risk
Download-page content and UI metadata only; no auth, data, or core runtime changes.

Overview
Adds asdf as a community install option on macOS and Linux in the download flow, with an English bash snippet that uses asdf v0.16+ (plugin add, install, set --home) and links to official getting-started docs.

Install-method dropdown icons are now optional: methods without an icon in config (asdf) get no iconImage, covered by a unit test. Types, constants.json, and English copy for the platform info blurb are updated accordingly.
