skip `.terraform` directories when searching for `discover_test.go`

[daniel-cit]

when searching for the integration test directory the hidden terraform folders .terraform should be skipped.

during development, if we use make docker_test_lint all dependencies are downloaded into the .terraform directories , which includes a version of the git repository for the modules used.

An example from the foundation:

cft test list

Error: found multiple discover_test.go files: [
"/workspace/3-networks/envs/shared/.terraform/modules/base_transitivity.templates/test/integration/discover_test.go"
"/workspace/3-networks/envs/shared/.terraform/modules/restricted_transitivity.templates/test/integration/discover_test.go" 
"/workspace/3-networks/modules/transitivity/.terraform/modules/templates/test/integration/discover_test.go"
"/workspace/5-app-infra/business_unit_1/development/.terraform/modules/base_shared_gce_instance.instance_template/test/integration/discover_test.go"
"/workspace/5-app-infra/business_unit_1/non-production/.terraform/modules/base_shared_gce_instance.instance_template/test/integration/discover_test.go"
"/workspace/5-app-infra/business_unit_1/production/.terraform/modules/base_shared_gce_instance.instance_template/test/integration/discover_test.go"
"/workspace/5-app-infra/modules/env_base/.terraform/modules/instance_template/test/integration/discover_test.go"
]. 
Exactly one file was expected
