Using phrasing from https://openinfra.org/legal/ai-policy (with just
"commit" replaced by "submission", because we do not submit changes
as commits but rather emails), clarify that the contributor remains
responsible for its copyright or license status.
[This is not my preferred phrasing. I would prefer something lighter
like "the "Signed-off-by" label in the contribution gives the author
responsibility". But for the sake of not reinventing the wheel I am
keeping the exact words from the OpenInfra policy.]
