fix: correct properties for TaskUpdate

[mvolfik]

this one is getting stale, can someone more informed than me review this please? maybe @valekjo?

[valekjo]

The editable properties are:

export const ACTOR_TASK_EDITABLE_FIELDS = ['description', 'input', 'name', 'title', 'options'];

So this is ok, unless we're aiming to make it complete (I'm not sure if we're planning to keep the api docs like this).

not sure if the openapi specs are more up to date or they need the same fix (https://docs.apify.com/api/v2-new#tag/Actor-tasks/operation/Updatetask)
