[Console] Suppress `proc_open` errors within `Terminal::readFromProcess`

When instantiating `SymfonyStyle` in a command it will try to determine the maximum width of the current console interface.

https://github.com/symfony/symfony/blob/6687e4ea35f45ebd73fb0315938103628cfb13a0/src/Symfony/Component/Console/Style/SymfonyStyle.php#L53

This will execute `stty -a | grep columns` down the line. Access to `stty` might be disallowed however, resulting in the following error:

```
ErrorException: Warning: proc_open(): Exec failed: Permission denied
#16 /vendor/symfony/console/Terminal.php(220): Symfony\Component\Console\Terminal::readFromProcess
#15 /vendor/symfony/console/Terminal.php(204): Symfony\Component\Console\Terminal::getSttyColumns
#14 /vendor/symfony/console/Terminal.php(170): Symfony\Component\Console\Terminal::initDimensionsUsingStty
#13 /vendor/symfony/console/Terminal.php(153): Symfony\Component\Console\Terminal::initDimensions

#11 /vendor/symfony/console/Style/SymfonyStyle.php(55): Symfony\Component\Console\Style\SymfonyStyle::__construct
#10 /vendor/symfony/messenger/Command/ConsumeMessagesCommand.php(136): Symfony\Component\Messenger\Command\ConsumeMessagesCommand::interact
#9 /vendor/symfony/console/Command/Command.php(311): Symfony\Component\Console\Command\Command::run
```

(Stack Trace actually from Symfony 6)

The phpDoc of `Terminal::getSttyColumns` states

> Runs and parses stty -a if it's available, _suppressing any error output_.

The latter might refer to `['suppress_errors' => true]` (though I am not sure) - which is a Windows only functionality. In any case, since `Terminal::readFromProcess` already checks for

```php
if (!$process = proc_open(…)) {
    return null;
}
```

and

```php
if (!\is_resource($process)) {
    return null;
}
```

upstream in Symfony 6/7, indicating that `proc_open` might fail - this error can additionally be suppressed using `@`. Besides, `Process::start` also uses ``@proc_open`` (added in symfony/symfony@099481f "Prevent warning in proc_open()").
