[DO NOT MERGE] Experimentally change consumer topic auto-create default

[AndrewJSchofield]

KIP-361 introduced a consumer config allow.auto.create.topics which enables a consumer subscribing to a non-existent topic to create it automatically. Initially, it defaulted to true, but the eventual plan was to change the default to false. This PR changes the default.

@AndrewJSchofield #17881 adds a "triage" label to PRs from non-committers. Turns out this also affect committers if their membership visibility in the ASF GitHub org is not public. I added instructions for setting your membership visibility to public https://github.com/apache/kafka/blob/trunk/.github/workflows/README.md#pr-triage
