fix(ci): remove dev OIDC mount to fix HTTP 500 in single-user/multi-user-basic

The dev OIDC app was mounted for all profiles but composer install only
ran for Playwright profiles, causing a missing vendor/autoload.php fatal
error that broke all /apps/* and /ocs/* routes. The hook script already
has app store fallback logic, so removing the dev mount is sufficient.
