faster process linter

[staabm]

Is your feature request related to a problem?

As reported in php/php-src#10024 php -l is dominated by process-creation overhead.
therefore with php/php-src#10710 (since php 8.3+) php -l allows to parse multiple files at once which make it considerably faster

Describe the solution you'd like

when parallel-lint is running with PHP 8.3+ it would be great it could utilize this new capability to speedup the process.

Additional context (optional)

• I intend to create a pull request to implement this feature.

the idea was already implemented in other php linting projects, which proofed a significant gain in performance.
