Subject: [PATCH] fix(flink): add Apache license header to muttley/README.md

PR #18394 added hudi-flink-datasource/hudi-flink/src/main/java/org/apache/hudi/sink/muttley/README.md
without an Apache license header, causing apache-rat:check to fail on every
new build of master ("Too many files with unapproved license: 1").

Prepend the standard Apache 2.0 HTML-comment license header so RAT passes.

Verified locally:
  cd hudi-flink-datasource/hudi-flink
  mvn -Pflink1.20 -Dscala-2.12 apache-rat:check
  -> Rat check: Summary over all files. Unapproved: 0
