feat: regenerate google-shopping packages (#17072)

This Pull Request drops support for Python <=3.9 in generated packages.
This is part of our ongoing effort to modernize the Cloud Python SDK
libraries and remove support for End-of-Life (EOL) Python versions.

## Changes
- Removed Python <=3.9 from testing, configuration, and constraints
files.
- Resolved dependency conflicts arising from dropping Python <=3.9
support.
- Cleaned up obsolete code related to Python <=3.9 support.
- Updated select copyright dates
- Updated some autogenerated headings
- Updated some tests to resolve issues discovered during this migration.
