This reverts commit 13956265c1.
The Wikimedia CI jobs running phan were installing mediawiki development
dependencies which might overlap with the dependencies from the
extension. Ultimately phan failed with:
includes/RemoteSchema.php:9
PhanRedefinedInheritedInterface
\RemoteSchema inherits abstract Interface \JsonSerializable declared at
internal:0 which is also declared at
../../vendor/jakub-onderka/php-parallel-lint/src/JsonSerializable.php:4.
This may lead to confusing errors.
If7171a6d46473b0bb05e3adaeb40229e7881c2b6 adjusts the CI configuration
to no more install MediaWiki core development dependencies and solely
relies on mediawiki/vendor.git. That prevents the duplicate interface
definition.
