fix: mock aws data sources in tests

[gberenice]

what

• Added mock_provider blocks to both test files.
• Mocked aws_ssm_parameter data source to avoid AWS credential requirements.

why

• Tests were failing with missing provider errors and AWS authentication issues:

│ Error: Invalid provider configuration
│ 
│ Provider "registry.opentofu.org/hashicorp/aws" requires explicit
│ configuration. Add a provider block to the root module and configure the
│ provider's required arguments as described in the provider documentation.

Ah that was why!

@oycyc please ignore this PR for now. I see a weird issue when the workflow file is valid, while the wrong SHA is used during the tests.
I'll make sure to ping you when this is resolved.
