Add support for skip-schema-validation in helm module (#995)

SUMMARY
This pull request adds support for a new skip_schema_validation option to the helm module, allowing users to disable JSON schema validation for Helm charts and values (requires helm >= 3.16.0).
ISSUE TYPE

Feature Pull Request

COMPONENT NAME
helm
ADDITIONAL INFORMATION
Added the skip_schema_validation boolean parameter to the helm module, allowing users to disable JSON schema validation for charts and values. This option is only available with Helm versions >= 3.16.0, and an appropriate error is raised for older versions.
Added integration tests to verify the behavior of the skip_schema_validation option, including cases for both supported and unsupported Helm versions.
Closes #994
