Adding Datadog secrets checks for all regions

Description

Being able to check for valid datadog keys on all regions

Preferred Solution

Sending an API check on every region or configure a specific region check to validate if it's a false positive or not. Right now it only checks the US1.

Additional Context

Checking only in the US1 region can lead to false true positives. Keys can be valid and just marked as false positives and nobody bothers to check them, since they're unverified (maybe old keys).
