This pull request simplifies and improves the automation for updating
Safari version policies on macOS by switching from a multi-line YAML
query to a single-line query and streamlining the associated update
script. The changes make the update process more robust, easier to
maintain, and less error-prone, especially when parsing and updating the
policy file.
**Policy and script simplification:**
* Converted the `query` field in `update-safari.yml` from a multi-line
YAML block to a single-line statement, reducing complexity and making it
easier to update programmatically.
**Script robustness and maintainability:**
* Updated `.github/scripts/dogfood-policy-updater-latest-safari.sh` to
extract and update the single-line `query` instead of handling a
multi-line block, greatly simplifying the parsing and replacement logic.

* Improved error handling for environment variables, requiring only the
essential `DOGFOOD_AUTOMATION_TOKEN` to be set, and clarified error
messages.
* Enhanced validation of the Safari feed response by checking for valid
JSON and explicit API errors using `jq`, making the update process more
reliable.
* Changed the update workflow to write changes directly to the file and
rely on GitHub Actions to create pull requests, removing the script's
own git and PR logic for a cleaner CI/CD process.
