Repository rulesets had a bug where UpdateRulesetClearBypassActor failed to clear bypass actors because it sent {"bypass_actors":null} instead of {"bypass_actors":[]}. This was fixed in PR #3727 (issue #3726) by explicitly initializing BypassActors with an empty slice.

The same bug exists in organization and enterprise rulesets:

• Organizations.UpdateRepositoryRulesetClearBypassActor
• Enterprise.UpdateRepositoryRulesetClearBypassActor

Both functions construct rulesetClearBypassActors{} with BypassActors uninitialized (nil).
