[MINOR] Remove outputdir .asf.yaml

Currently the format of the .asf.yaml sends emails to everyone on all commits. According to https://issues.apache.org/jira/browse/INFRA-26700 the error is in our project. This commit, therefore, removes the outputdir, as specified in: https://github.com/apache/infrastructure-asfyaml?tab=readme-ov-file#jekyll-cms
