fix: minimize changes - revert stubs.json, fix h2 test logic, trim comments

- wiremock: delete bundled stubs.json (remote URL is working again) and
  revert create-stubs.sh to simple download-only version
- typedb: replace xfail with proper fix — drop http2=True and HTTP/2
  version assertions; test now verifies HTTPS connectivity via HTTP/1.1
  with a concise comment explaining the upstream ALPN regression
- miniflare: trim INTRODUCED-BY block from extension.py comment; full
  commit reference and root cause details moved to PR description
