Remove support for PHP 8.0, Remove hard dependency on service manager

[gsteel]

Further to discussion in #75, removing the hard-dependency on laminas/service-manager here allows consumers to use the component in projects that require psr/container:2, providing they only use the StandaloneExtensionManager for Reader\ and Writer\

Ughh - we have to drop PHP 8.0 and work around the BC break in tests introduced in SM 3.21

@gsteel
Thanks for the quick solution! 👍🏻

@MegaChriz
Can you check this?

Thanks for picking this up so quickly! On my local install I have PHP 8.1 and that looked to go well. I saw that on a composer update on a Drupal 10 install that laminas/laminas-servicemanager got removed. Unit and Kernel tests for Feeds still passed. The Functional tests I did not run yet, as they take more time to run on my local machine.

I hope to test with PHP 8.2 soon!

Feeds does indeed use \Laminas\Feed\Reader\StandaloneExtensionManager.

These are other classes/interfaces that Feeds uses:

• Laminas\Feed\Reader\Exception\ExceptionInterface
• Laminas\Feed\Reader\ExtensionManagerInterface
• Laminas\Feed\Reader\Reader
• Laminas\Feed\Reader\Extension\AbstractEntry
• Laminas\Feed\Reader\FeedSet

This just needs an approving review from someone on the @laminas/technical-steering-committee and it can be released

Feeds tests pass
I ran all Feeds tests locally now on PHP 8.2.8 and all that are at least related to parsing RSS Feeds passed!

Feeds can now be installed using composer
I also tested if I could install drupal/feeds on PHP 8.2.8 now by using the following definitions in composer.json of a local project:

"repositories": [
   (...)
   {
        "type": "vcs",
        "url": "https://github.com/gsteel/laminas-feed.git"
    }
],

"require": {
   (...)
    "laminas/laminas-feed": "dev-remove-hard-dependency-on-service-manager as 2.13"
},

With that I could require drupal/feeds with success!
(And without the changes from this issue composer reports that the requirements could not be resolved.)

LGTM, thanks @gsteel!
