Prevent installation with incompatible symfony/process versions

Sadly, `symfony/symfony` declared `php:>=7.1` compatibility many moons ago: that is generally technical lack of vision and responsibility on their end, but that ship has sailed. This means that a `composer update` can and **will** install a dependency graph that is incompatible with your system's dependencies. This change prevents installation of `symfony/process` in versions too archaic to actually function. As a side-effect, `vimeo/psalm` was also upgraded to its latest and greatest.
