fix(workflows): also exclude *AbstractTest.php suffix from Mage-OS suite (#374)

* fix(workflows): exclude abstract test base classes from Mage-OS suite

PHPUnit 12 treats discovered Abstract*Test.php files as runner warnings,
which the integration job interprets as exit code 1 even when all concrete
tests pass. Generate <exclude> entries for any Abstract*Test.php inside
the included shards. Also fix unescaped backticks in the trailing echo so
bash no longer logs "integrationIgnore: command not found".

* fix(workflows): also exclude *AbstractTest.php suffix form

Prior commit only matched Abstract*Test.php prefix; upstream Magento
also ships abstract bases with the suffix form (PaypalExpressAbstractTest,
EntityAbstractTest, EavAbstractTest, etc.), which still trip PHPUnit 12
runner warnings and turn shards red.
