Add the ability to set JSON default value as an array

[msmakouz]

Added the ability to use an array as a default value in JSON columns.

AbstractColumn

$column = $schema->json('settings')->defaultValue(['theme' => 'dark']);

Migrations (with cycle/migrations package)

public function up(): void
{
    $this->table('users')
        ->addColumn('settings', 'json', ['nullable' => false, 'default' => ['theme' => 'dark']])
        ->create();
}

Attributes (with cycle/orm and cycle/annotated packages)

use Cycle\Annotated\Annotation\Column;
use Cycle\Annotated\Annotation\Entity;

#[Entity]
class User
{
    // ...

    #[Column(type: 'json', default: ['theme' => 'dark'])]
    private array $settings;

    // ...
}

Closes: #54
