Subject: [PATCH 1/2] infra(build): serve install.sh from site root via
 postbuild download

Mirrors the portal's download-redirected-files.sh pattern: a postbuild
script fetches the ICP SDK installer from the sdk public-manifest branch
and places it at dist/install.sh so it is served at /install.sh.

Required because internetcomputer.org/install.sh now redirects to
docs.internetcomputer.org/install.sh and we were returning 404.
