Symfony version(s) affected: 5.3.5

Description
Uncaught PHP Exception TypeError: "Argument 1 passed to str_contains() must be of the type string, null given, called in vendor/symfony/http-foundation/Response.php on line 327" at vendor/symfony/polyfill-php80/bootstrap.php line 29

from Response.php:327:

if ('1.0' == $this->getProtocolVersion() && str_contains($headers->get('Cache-Control'), 'no-cache')) {

It seems that happens when $headers->get('Cache-Control') is null.

How to reproduce
Request with missing 'Cache-Control' header

Possible Solution
Pass default value '' in the second argument of get()
$headers->get('Cache-Control', '')

Additional info
phpDoc claims that method \Symfony\Component\HttpFoundation\HeaderBag::get can return string|null,
but str_contains can receive only string in the first argument

I can create PR with this solution
