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.

I'm merging and bypassing the rules because we have a chicken-egg problem here. Tests will fail untill I merge the fix into the main.
