fix(examples): update openai-responses pyproject.toml and basic-examples README (HYBIM-823)

openai-responses/pyproject.toml was the source-of-truth for the compiled
requirements.txt — also rename galileo there. README in basic-examples had a
pip install snippet still referencing galileo.

Note: requirements.txt in openai-responses cannot be recompiled until splunk-ao
is published to PyPI; the hand-edited lockfile entry will self-correct post-publish.
