PHP Fatal error: Uncaught Error: Call to undefined function str_contains() in phar:///.../phpstan.phar/src/Turbo/TurboExtensionSelector.php:113 #15137

Bug report

I'm running Rector under PHP7.4 and since this commit: phpstan/phpstan-src@51d272f I get a fatal error. I see that phpstan requires the symfony/polyfill-php80 but somehow it doesn't use the polyfill method

Expected output
