Update Laravel Version

[sean-dickinson]

Goal

• Update the Laravel version from 10 to 11

Considerations

• Only update what is necessary to make the app continue to work
• Consider if the local environment needs to be updated in any way (docker-compose)
• Ensure the application can still be set up using the Readme instructions
• We do not need to migrate existing environments, this is a template repository used for a code challenge so no one will need to do an upgrade in place, we just need to ensure it works correctly when setting it up fresh.
