Related to https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/4445 It seems like ansible-core 2.19.0 no longer automatically parses template lookup content as JSON (into a dict) when dealing with template files (be it `file.json.j2` or `file.j2`). For files detected to contain YAML (`.ya?ml.j2`, but possibly others), it automatically parses YAML, because the `convert_data` option for the template lookup defaults to `true`.
