Subject: [PATCH 3/3] Fix CI: allow Composer to resolve deps with known
 advisories

Composer 2.10 blocks dependency resolution when packages have security
advisories, which breaks install for phpunit ^5 and its transitive
symfony/yaml requirement. This project has dev-only dependencies, so
disable advisory blocking via config policy.advisories.block.

Also rename the invalid setup-php input extension-csv to extensions.
