feat: Add new test cases for LoadConfigs

[Aisuko]

Description

This PR fixes #262

• settings.json can help the contributor to more easily debug the project by using VSCode debug features but it should not include any default values.
• Replacing the deprecated args of ginkgo--flakeAttempts to --flake-attempts
• Replacing the ioutil.ReadDir(path) to os.ReadDir(path) and adding a test case for it. ioutil.ReadDir was deprecated in go v.1.19, more detail. here: https://pkg.go.dev/io/ioutil#example-ReadDir
