chore: improve monitoring for Missing exception filter causes expected FORBIDDEN

Registered the new `WorkflowQueryValidationGraphqlApiExceptionFilter` on two resolvers that call code paths throwing `WorkflowQueryValidationException`:

1. **`workflow-version-step.resolver.ts`** — handles `UpdateWorkflowVersionStep` (the mutation in this Sentry error)
2. **`workflow-version-edge.resolver.ts`** — handles edge operations that also call `getValidatedDraftWorkflowVersion`

With the filter registered, `WorkflowQueryValidationException` is now converted to a `ForbiddenError` (`BaseGraphQLError` with `ErrorCode.FORBIDDEN`). The `shouldCaptureException` function in the GraphQL error handler hook will now correctly filter this out (since `FORBIDDEN` is in `graphQLErrorCodesToFilter`), eliminating the Sentry noise from this expected validation error.
