fix/rego query

[gertd]

The PR adds input rule validation to the Is function using the new runtime.ValidateRule() function, which verifies if the rule exists in the active bundle.

Add runtime.ValidateQuery() check to DecisionTree implementation, which retrieves the rules list from the policy list AST, so these always exist and do not need additional validation using ValidateRule()

Additional updates:

• Remove obsolete PolicyInstance param from runtime and templates
• Remove PolicyInstance middleware
• Disable the mig010, migration to minimize the change of this PR
• Update dependencies
