Install stty required for tests on ubuntu-latest

[bocharsky-bw]

In every test job we have skipped tests:

Run vendor/bin/simple-phpunit -v
PHPUnit 9.5.4 by Sebastian Bergmann and contributors.

Runtime:       PHP 8.0.5
Configuration: /home/runner/work/demo/demo/phpunit.xml.dist
Warning:       Your XML configuration validates against a deprecated schema.
Suggestion:    Migrate your XML configuration using "--migrate-configuration"!

Testing 
SSSS...........................................                   47 / 47 (100%)

There were 4 skipped tests:

1) App\Tests\Command\AddUserCommandTest::testCreateUserNonInteractive with data set #0 (false)
`stty` is required to test this command.

/home/runner/work/demo/demo/tests/Command/AddUserCommandTest.php:35

2) App\Tests\Command\AddUserCommandTest::testCreateUserNonInteractive with data set #1 (true)
`stty` is required to test this command.

/home/runner/work/demo/demo/tests/Command/AddUserCommandTest.php:35

3) App\Tests\Command\AddUserCommandTest::testCreateUserInteractive with data set #0 (false)
`stty` is required to test this command.

/home/runner/work/demo/demo/tests/Command/AddUserCommandTest.php:35

4) App\Tests\Command\AddUserCommandTest::testCreateUserInteractive with data set #1 (true)
`stty` is required to test this command.

/home/runner/work/demo/demo/tests/Command/AddUserCommandTest.php:35

OK, but incomplete, skipped, or risky tests!
Tests: 47, Assertions: 92, Skipped: 4.

Remaining indirect deprecation notices (1)

  1x: The "DAMA\DoctrineTestBundle\Doctrine\DBAL\AbstractStaticDriverV2" class implements "Doctrine\DBAL\Driver\ExceptionConverterDriver" that is deprecated.
    1x in PHPUnitExtension::executeBeforeFirstTest from DAMA\DoctrineTestBundle\PHPUnit

It would be good to run those tests at least on Ubuntu I think

Looks like the stty check wasn't perfect and does not work for GitHub actions. I simplified the condition to actually test those commands on GitHub actions for Ubuntu / Mac OS. If anyone will have problems running tests on their Ubuntu / Mac OS - please, feel free to tweak that part and make sure tests are not skipped on GitHub Actions. But so far tests are green with these changes now :)

Failed "Lint / Linters" was fixed in a separate PR, see #1227

Thanks a lot Victor. You are right that we can later tweak this as needed ... but for now, it's great to test these commands on GitHub actions again. Thanks!
