`CreatePoll` uses `u8` for the expiry hours, despite Discord docs now allowing up to 32 days

[jamesbt365]

Official docs: https://discord.com/developers/docs/resources/poll#poll-create-request-object

serenity/src/builder/create_poll.rs

Lines 33 to 42 in d1ab1f1

	pub struct CreatePoll<Stage: Sealed> {
	question: CreatePollMedia,
	answers: Vec<CreatePollAnswer>,
	duration: u8,
	allow_multiselect: bool,
	layout_type: Option<PollLayoutType>,
	#[serde(skip)]
	_stage: Stage,
	}

Note that the docs also need to be changed to mention the new limit.

serenity/src/builder/create_poll.rs

Lines 115 to 131 in d1ab1f1

	impl CreatePoll<NeedsDuration> {
	/// Sets the duration for the Poll to run for.
	///
	/// This must be less than a week, and will be rounded to hours towards zero.
	pub fn duration(self, duration: std::time::Duration) -> CreatePoll<Ready> {
	let hours = duration.as_secs() / 3600;
	CreatePoll {
	question: self.question,
	answers: self.answers,
	duration: hours.try_into().unwrap_or(168),
	allow_multiselect: self.allow_multiselect,
	layout_type: self.layout_type,
	_stage: Ready,
	}
	}
	}
