Description

BrevoRequesstParser handles 'tags' as a mandatory parameter, when it's not.
https://github.com/symfony/brevo-mailer/blob/7.0/Webhook/BrevoRequestParser.php#L52C1-L53C1

Brevo's documentation doesn't clarify, but 'tags' aren't mandatory parts of the request.

https://developers.brevo.com/docs/transactional-webhooks#sent

How to reproduce

• setup webhook url in your Brevo settings
• click on "test" button
• the webhook API will reject all test requests with 406 (it's fails on the part !isset($content['tags']))

Also if you send any emails without adding some TagHeader to the email, all related webhook event will be rejected for the same reason.

Possible Solution

Remove !isset($content['tags']) condition from doParse method in Symfony\Component\Mailer\Bridge\Brevo\Webhook\BrevoRequestParser
