[11.x] Fix SesV2Transport to use correct EmailTags argument

[Tietew]

Illuminate\Mail\Transport\SesV2Transport calls SESv2's SendEmail API but passes v1's Tags argument. The call doesn't fail but the tags are not attached to the sent email.
(ConfigurationSet events don't include specified tags)

This PR fixes the parameter name to correct EmailTags.

Notes:

• Please don't confuse that SesTransport uses SES v1, which argument name is Tags.
• Laravel 10.x has same issue. Backport will be needed.

Reference:

• https://docs.aws.amazon.com/ja_jp/aws-sdk-php/v3/api/api-sesv2-2019-09-27.html#sendemail

Steps:

class TestMail extends Mailable
{
    public function envelope(): Envelope
    {
        return new Envelope(subject: 'blah blah blah', metadata: ['Foo' => 'Bar']);
    }
}

The ConfigurationSet event Before:

{
    "eventType": "Delivery",
    "mail": {
        ...
        "tags": {
            "ses:operation": ["SendRawEmail"],
            ...
        }
    }, ...
}

After:

{
    "eventType": "Delivery",
    "mail": {
        ...
        "tags": {
            "ses:operation": ["SendRawEmail"],
            ...
            "Foo": ["Bar"] // <- HERE
        }
    }, ...
}
