Stop testing PHP 7.4, 8.0 and Drupal 9

[mglaman]

Managing this project would be much easier if PHP 7.4 and PHP 8.0 were dropped. This would also stop Drupal 9 testing; or a Drupal 9 job could be created with PHP 8.1.

webflo/drupal-finder was raised to PHP 8.1 in its 1.3 release. I'm afraid it'll get more complicated with D11, PHPUnit 10/11.

Proposal:

• bump minimum PHP version to PHP 8.1
• drop testing D9
• drop lower versions of Drush, etc, which allowed D9 testing

this would trigger the 1.3.0 release

This makes sense to me. 👍🏻

PHP 8.1 is only supported next 1.5 years
D9 surely needs phase out

[mglaman]

PHP bumped to 8.1. Technically D9 can be supported, if it was removed the following tests/rules could be dropped:

• AccessDeprecatedConstantTest, and probably \mglaman\PHPStanDrupal\Rules\Deprecations\AccessDeprecatedConstant
• \mglaman\PHPStanDrupal\Tests\Rules\ClassExtendsInternalClassRuleTest::testRule ContentEntityDeleteForm test case
• ConditionManagerCreateInstanceContextConfigurationRuleTest (and probably its rule)
• \mglaman\PHPStanDrupal\Tests\Rules\DeprecatedHookImplementationTest::testRule test for deprecated_field_widget_hooks_field_widget_form_alter
• \mglaman\PHPStanDrupal\Tests\Rules\GetDeprecatedServiceRuleTest::testRuleDrupal8
• \mglaman\PHPStanDrupal\Tests\Rules\GetDeprecatedServiceRuleTest::testRuleDrupal9
• \mglaman\PHPStanDrupal\Tests\Rules\RequestStackGetMainRequestRuleTest::testRule and the rule
• \mglaman\PHPStanDrupal\Tests\Rules\SymfonyCmfRouteObjectInterfaceConstantsRuleTest::testRule and the rule
• \mglaman\PHPStanDrupal\Tests\Rules\SymfonyCmfRoutingInClassMethodSignatureRuleTest::testRule and the rule

Personally, I have no need for Drupal 9 support. Generally, favoring accelerated + efficient development over legacy maintenance seems like a good idea.

PHP 7.4/ 8.0 support has been dropped already, D9 is the only one still standing.

A new branch might be a nice clean cut-off point to drop D9 support?

We can say 2.x drops Drupal 9 support, as a follow up to his PR.
