Remove outdated Build 20262+ requirement; update VS Code extension link

* Remove outdated Build 20262+ requirement; update VS Code extension recommendation

- Remove 'must be running Build 20262+' note — all supported Windows 10/11
  versions exceed this 2020 Insider build requirement; the note adds noise
  without value. Retained the link to the WSL installation page as a note
  for users wanting a different distro or manual steps.
- Update VS Code recommendation: point to the standalone WSL extension
  (ms-vscode-remote.remote-wsl) instead of the full Remote Development
  extension pack, consistent with current VS Code docs and PR #2517.

* Address Copilot review: fix typo, add correct wsl --install prerequisite

- Fix 'set-by-step' typo in front-matter description
- Add correct Windows prerequisite for wsl --install:
  version 2004 (Build 19041+) or Windows 11 — replacing the removed
  Build 20262+ note which cited an Insider-only build number
