chore: add option to create package with cypress configuration (SAP#11299)

Added a new `test-setup` flag to the create package script.

This flag supports two options `--test-setup <"cypress" | "manual">`

- When set to `cypress`, the generated package will include a predefined Cypress configuration to enable component testing.
- When set to `manual`, no test configuration will be included, allowing it to be configured separately.
