test: ✏️ Add unit tests for code signing functions
- Introduced new test files `Invoke-PSBuildModuleSigning.tests.ps1` and `New-PSBuildFileCatalog.tests.ps1` to cover the functionality of code signing. - Removed the old `Signing.tests.ps1` file to streamline test organization. - Ensured tests validate the existence, parameters, and expected behaviors of the `Invoke-PSBuildModuleSigning` and `New-PSBuildFileCatalog` functions. - Added checks for help documentation and parameter validation, including mandatory parameters and default values.
