Why

Closes #173

Also, I've added the $queries attribute in the class definition as PHP 8 deprecated dynamic attributes

Checklist

• Cloned the repository, set $ALFRED_PKGMAN_WORKFLOW_DIR, and ran make to use your cloned code as the active Workflow in Alfred
• Optionally, include a large icon in the src/icon-src/ folder that is square.
• Optionally, include a cached icon in the src/icon-cache/ folder, sized to 256x256 pixels. Alfred creates these when you insert an image into a workflow. You can get this from inside the .alfredworkflow. Right-click the workflow in Alfred, click Show in Finder. The --hash-value--.png file will be in that folder. Copy to src/icon-cache and rename.
• Optionally, add a screenshot. Use ⌘ (command) + ⇧ (shift) + 4, press ␣ (space), then click on the Alfred window to create a clean screen shot. Place in the screenshots folder
• Update README.md with any necessary or changed documentation, and any new screenshots.
• Increment the version number of the workflow following (Semantic Versioning)[https://semver.org]
• Run make release to package up your changes & copy the Workflow & its info.plist to the root of the repository, and commit those two changes on their own, e.g., Bump to 5.1.1
