fix(sdk): detect versioned PHP binaries such as php8.1 on PATH

PHP discovery matched only the exact name php on PATH, so Debian and Ubuntu installs with several versions (ppa:ondrej/php, packages.sury.org) listed only the alternatives default. PATH directories are now also scanned for php<version> (php8.1, php81), skipping shim directories and the php-cgi / phpize / phpdbg helpers. The plain php comes first, so deduplication by real path keeps /usr/bin/php over the php8.3 it links to.
