fix: add missed isTtySupported() method

[upyx]

Fixes fatal error #90 by adding missed isTtySupported() method.

Description

It copies the isTtySupported() static method from Symfony's Process to the abstract ProcessCommand. Additionaly it excluded Composer >=2.3 from composer.json and removed the deprecated totallyTyped Psalm option.

Motivation and context

Version 1.3.0 doesn't work with PHP 8. Version 1.4.0 doesn't work at all. I'd like to use devtools with PHP 8. Fixes #90

How has this been tested?

composer self-update --2.2
composer update
