migrate test runs from travis to github actions

[falkenhawk]

also includes php 8.0 and php 8.1, with allowance to fail

looks good 👍 one more thing I would change

@marcing @partikus I have no idea why it fails on php 5.x. On travis it worked fine https://app.travis-ci.com/github/ovos/doctrine1/jobs/513037759

I cannot spend more time on this, I am leaving this for you

I believe for PHP 5.3 we should use:

if (PHP_VERSION_ID >= 50300) {
            $this->assertEqual($xml, '<?xml version="1.0" encoding="utf-8"?>
<data><User id="4" type="0" email_id="1"><name>zYne</name><loginname/><password/><created/><updated/><Phonenumber><Phonenumber id="2" entity_id="4"><phonenumber>123 123</phonenumber><Entity/></Phonenumber></Phonenumber></User></data>
');
        } else {
            $this->assertEqual($xml, '<?xml version="1.0" encoding="utf-8"?>
<data><User id="4" type="0" email_id="1"><name>zYne</name><loginname></loginname><password></password><created></created><updated></updated><Phonenumber><Phonenumber id="2" entity_id="4"><phonenumber>123 123</phonenumber><Entity></Entity></Phonenumber></Phonenumber></User></data>
');
        }

but then, the bugfix does not make sense 😮
