Use correct attribution in the footer of documentation pages (monorepo)

[andygrove]

Describe the enhancement requested

To be inline with ASF policy, we should update the text in the footer used in the docs (e.g. https://arrow.apache.org/docs/cpp/streaming_execution.html) to match the footer used in the main website (https://arrow.apache.org/). i.e. add the trademark attribution test.
