User Story

As a developer, I need to ensure that the "data-center" props in validation constraint unit test content files have the right namespace, so that the unit tests for the FedRAMP external constraints yield the expected results.

Goals

Need to remove the FedRAMP namespace from the "data-center" prop in the following files:

• src/validations/constraints/content/ssp-data-center-US-INVALID.xml
• src/validations/constraints/content/ssp-data-center-alternate-INVALID.xml
• src/validations/constraints/content/ssp-data-center-count-INVALID.xml
• src/validations/constraints/content/ssp-data-center-country-code-INVALID.xml
• src/validations/constraints/content/ssp-data-center-primary-INVALID.xml
• src/validations/constraints/content/ssp-all-VALID.xml
