GH Actions: fix phar creation

The `phar` file should only contain the files of PHP Parallel Lint and any non-dev requirements. It should not include the `dev` requirements of this package.

As things were, it did.

Fixed now, by doing the `composer install` with the `--no-dev` option, both for the Test workflow as well as for the Release workflow.
