Documentation: ID Header section is confusing

[ThomasLandauer]

First: Is this the right place to report errors in the docs https://swiftmailer.symfony.com/docs/introduction.html ? No repo to submit a PR?

It's about https://swiftmailer.symfony.com/docs/headers.html#id-headers

• Minor typo: "Changing the value of an existing date header is done by calling its setId() method" => "of an existing ID header"
• Major: IMO, The entire section is overly complicated. Most people probably just want to set the Message-ID header, nothing else. I mean: Who uses a custom ID header? What for?
  Also the text keeps switching between talking about the "official" Message-ID and those custom ID-headers. When following the examples, it can lead to this issue: addIdHeader() produces duplicate Message-ID header #984
  So I think the entire section should be re-written completely.

I'm closing this, since Swift Mailer is going to be replaced by Symfony Mailer.
