StaticPrefixCollection error handling broken when PHP is using libpcre2-10.43

[Lustmored]

Symfony version(s) affected

7.0.3

Description

The error message for lookbehind assertion of not fixed length has changed in new libpcre2 version to:

Compilation failed: length of lookbehind assertion is not limited at offset 0

This breaks error handling in StatixPrefixCollection::handleError, which checks for:

public static function handleError(int $type, string $msg): bool
{
        return str_contains($msg, 'Compilation failed: lookbehind assertion is not fixed length');
}

Downgrading libpcre2 solves the issue.

How to reproduce

1. Update system to libpcre2-10.43 (on Gentoo systems this gets pulled automatically)
2. Run symfony console cache:clear on a project with declared route prefixes

Can you please send a PR to fix this? I guess it should target branch 5.4?
