Duplicate key members holding rule ID

#### Description of problem:
During our work on https://github.com/ComplianceAsCode/content/pull/9870, we have discovered that some templates require to be passed both `_rule_id` and `rule_id` variables in their parameters. But, they both seem to contain the same value.
Some parts of our code use the former, other parts use the latter. That's confusing and complicates the logic.

For detailed analysis, see the discussion in https://github.com/ComplianceAsCode/content/pull/9870/files#r1031371254.

To solve this we should perform refactoring and unify the code and variable usage.
