Laravel Web3 Versions Save

Forcing PHP 8.1+ due to formatting constraints of a package

• Upgrade to Laravel 9.x (https://github.com/renoki-co/laravel-web3/pull/27)
• Dropped Laravel 7.x/8.x

The old Web3 package is obsolete, so we can say welcome to PHP Web3, made by @nunomaduro and his contributors. (https://github.com/renoki-co/laravel-web3/pull/21)

Before upgrading, take these steps into account:

• provider and request_manager keys from each connection should be dropped
• The only available methods to call from the facade class are the ones shown in the documentation (personal, shh, utils, getProvider methods got removed)

• Dropped PHP 7.4

• Fixed bindings to work with Laravel Octane
