This issue type is denoted by the type SemanticIssueType.ROLLOUT_PERCENTAGE_SUM_NOT_ONE_HUNDRED.

Such an issue is detected if a feature flag rule's valuesOnMatch array/its values have in total a rollout percentage sum that is not exactly 100%.

For each feature flag rule that has valuesOnMatch array with an incorrect rollout percentage sum, one issue of this type will be created.
