The ".twig.cache.inner" pool is a child of "cache.app". When the application
configures a natively tag aware adapter for it (redis, valkey, pdo or mongodb),
the child pool is already tag aware and decorating it with a TagAwareAdapter
turns every read into a miss.
Alias "twig.cache" to the pool in that case, the way Symfony aliases
"cache.app.taggable" to "cache.app" instead of decorating it. The pool keeps
its own namespace, so it does not start sharing the application pool's one, and
the decorator stays in place for the plain adapters that need it.
