(ci) test with lowest dependency required version

[Sysix]

At the moment we install all our dependencies with the highest minor & patch number.
Because this project support all major versions from the beginning (X.0) we should also test these specific versions too.

There is a composer command which will help us: --prefer-lowest
From the composer docs it suggest to also include --prefer-stable

This makes sense, thanks @Sysix. But the tests are failing. I think it's because of the PHPUnit dependency, but not quite sure.

PHP 8 Support is only available for phpunit 9.3:
https://github.com/sebastianbergmann/phpunit/milestone/38?closed=1

Also testbench support laravel 8 at version 6.*:
https://packages.tools/testbench.html

EDIT: when its still not working, we need to drop the phpunit 9 support. Should not be that much of a problem 🤞

PHPUnit 10 supports only PHP8.1. PHPUnit 9.5 removed the deprecation warning

Then another wierd Bug was happening with testbench < 6.24:

There was 1 failure:

1. Kirschbaum\PowerJoins\Tests\JoinRelationshipTest::test_has_one_of_many
   Failed asserting that 'select "posts".*, "comments"."body", max("votes") as "votes", "comments"."post_id" from "posts" inner join "comments" on "comments"."post_id" = "posts"."id" where "posts"."deleted_at" is null limit 1' contains "max("comments"."votes") as "votes_aggregate"".

/var/www/html/tests/JoinRelationshipTest.php:765

When requiring testbench 6.24 this bug is fixed. Don't know why :/

EDIT: I looked which version is tested for laravel. The tests require laravel 8.75.0 so we should also reflect that.

the CI overwrote our requirements. Updated the github workflow too :)

[luisdalmolin]

Still erroring. I'm not opposed on dropping support for outdated Laravel/PHP versions, if that helps

[Sysix]

I forgot one line to update.

Hey @Sysix, we updated this based on the latest master, but it appears to be broken as the testbench versions are now not being passed through to that installation command. It would be great if you had any ideas about what is wrong!
