PHP deprecated warning message

[tanaeakihiko]

What are you attempting to do
I'll tweet message.

Expected behavior
I don't get PHP waring message.

Actual behavior
I get PHP warning messages as bellow.

PHP Deprecated: Abraham\TwitterOAuth\HmacSha1::buildSignature():
Implicitly marking parameter $token as nullable is deprecated,
the explicit nullable type must be used instead in /app/vendor/abraham/twitteroauth/src/HmacSha1.php on line 32
PHP Deprecated: Abraham\TwitterOAuth\SignatureMethod::buildSignature():
Implicitly marking parameter $token as nullable is deprecated,
the explicit nullable type must be used instead in /app/vendor/abraham/twitteroauth/src/SignatureMethod.php on line 37
PHP Deprecated: Abraham\TwitterOAuth\Request::fromConsumerAndToken():

PHP Deprecated: Abraham\TwitterOAuth\Request::signRequest():

PHP Deprecated: Abraham\TwitterOAuth\Request::buildSignature():
Implicitly marking parameter $token as nullable is deprecated,
the explicit nullable type must be used instead in /app/vendor/abraham/twitteroauth/src/Request.php on line 271

Code example

$connection = new TwitterOAuth(...);
$connection->setApiVersion('2');
$res = $connection->post('tweets', ['text' => $message], ['jsonPayload' => true]);

Versions:

• TwitterOAuth: v7.0.0
• PHP: v8.4

Additional context
"PHP RFC: Deprecate implicitly nullable parameter types"
https://wiki.php.net/rfc/deprecate-implicitly-nullable-types

In PHP 8.4 or higher,
if we make code as like below,
function foo(T $var = null) {}
we get PHP warning message.
And in PHP 9, we'll get PHP Fatal error message.

Thank you for your nice product.
You have time to fix, I want to fix and make Pull Request.
