[php] disable php-cs progress bar output in CI

[olleolleolle]

🤔 What's changed?

This PR changes CI output slightly, for the php-cs-fixer, to reduce visual clutter.

Add --show-progress=none.

Read all the configuration options at https://github.com/PHP-CS-Fixer/PHP-CS-Fixer/blob/master/doc/usage.rst

⚡️ What's your motivation?

CI output needs hygiene, to be copy-pastable etc.

🏷️ What kind of change is this?

• :bank: Refactoring/debt/DX (improvement to code design, tooling, documentation etc. without changing behaviour)

📋 Checklist:

• [x] I agree to respect and uphold the Cucumber Community Code of Conduct

Did I misspell something, only test-codegen ran?

EDIT: The reason is that none of my editing touched a file path in the php/** glob pattern.

 push:
    branches:
      - main
      - renovate/**
    paths:
      - php/**
      - testdata/**

Alright, THIS WORKED!
