[BUG] PhpImap is not compatible with PHP8.4

[genyslt]

Environment (please complete the following information):

• PHP IMAP version: 5.0.1
• PHP Version: 8.4.5

Describe the bug
PhpImap\Mailbox::__construct(): Implicitly marking parameter $attachmentsDir as nullable is deprecated, the explicit nullable type must be used instead

To Reproduce
PHPSTAN

The used code:

$mailbox =  new Mailbox(
			$connection_strin,
			$username,
			$password,
			$attachmentsDir
		);

PhpImap\Mailbox::__construct(): Implicitly marking parameter $attachmentsDir as nullable is deprecated, the explicit nullable type must be used instead

I get something very similar:

deprecated: 8192 :: PhpImap\Exceptions\ConnectionException::__construct(): Implicitly marking parameter $previous as nullable is deprecated, the explicit nullable type must be used instead on line 16 of /home/mirko/Server/climat/vendor/php-imap/php-imap/src/PhpImap/Exceptions/ConnectionException.php

In summary, it seems to me that with php 8.4 arguments that accept null must be explicitly marked as nullable.

For example:

public function __construct(array $message, int $code = 0, Exception $previous = null)

shoud be:

public function __construct(array $message, int $code = 0, ?Exception $previous = null)

And for all similar cases.

Hi, is there anyone who is carrying on the development?

See #722 there's already a pull request for a while

Looks like this project/package is dead...
Maybe someone could create a new composer package, that contains the fix by #722?
Thanks!
