Serializable interface is depreciated.

[rakshit087]

• Laravel Version: 8.6.2
• PHP Version: 8.1.0RC1
• Database Driver & Version: None

Description:

After the PHP update 8.1, the Serializable interface is deprecated, however, illuminate/queue uses it, which is breaking the installation.

Steps To Reproduce:

1. Update Laravel to Latest Version (If you are using Globel Installation) and create a new application by laravel new example-app or directly create a new app by composer create-project laravel/laravel example-app
2. You will get this error Opis\Closure\SerializableClosure implements the Serializable interface, which is deprecated. Implement __serialize() and __unserialize() instead (or in addition, if support for old PHP versions is necessary)
   I am attaching relevant screenshots. :)

A PR for PHP 8.1 Support in opis/closure is already in draft state. opis/closure#103

Also for PHP 8.1 Support in Laravel is a PR currently on its way. #38404

Edit: Also please always use the latest laravel version (currently v8.59.0)
