chore: update linter configuration and enhance CI workflow

- Replaced 'exportloopref' with 'copyloopvar' in .golangci.yml for improved linting accuracy.
- Updated 'goerr113' to 'err113' for consistency in linter naming.
- Added Go setup step in the GitHub Actions workflow to specify Go version 1.23.
- Enhanced the gosec report upload process and added a step to display scan results in the CI workflow.
- Improved error handling in the unmarshalBody function to provide clearer error messages.
