Use Laminas namespaced Mime Decode instead of Zend_Mime_Decode

[peterjaap]

This fixes the unit test that fails here; https://github.com/Ethan3600/magento2-CronjobManager/actions/runs/6747747882/job/18418775492

Thanks for this @peterjaap. I can see there is a reference to \Zend\Mail\Message in this file too. Do we need to change that to something in the Laminas namespace as well?

Also, there doesn't seem to be any mention of Zend nor Laminas in composer.json; do we need to add something (to require-dev) to cover this?

@fredden well \Zend\Mail\Message is still used by Magento core itself too, so that should be fine.

It doesn't need to be added to the dependencies list, since these are part of Magento itself.

@fredden hmm now that I look closer, I don't see \Zend\Mail\Message being used in the Magento core but I'm pretty sure Laminas introduced something that atuomatically uses the Laminas namespaced one. That just doesn't work with the old way of naming classes with the underscores, like Zend_Mime_Decode does.

The error message has changed now, but I think that's to do with \Laminas\Mime\Decode::decodeQuotedPrintable() not actually decoding the quoted-printable string it's passed. I've reported this upstream, but a robot closed the issue immediately: laminas/laminas-mime#37.

I'll merge this in as it's clearly an improvement, even if the tests still fail.

Thanks @peterjaap 👍
