types(GuildAuditLogs): Allow fetching to return all possible values

[Jiralite]

Please describe the changes this PR makes and why it should be merged:
This resolves #8275. To explain: the issue was that calling <Guild>.fetchAuditLogs() (or <Guild>.fetchAuditLogs({ type: null })) would incorrectly assume that the returned action is always null, actionType is always ALL, extra is always null etc. instead of leaving these as all possible values.

A code sample of how this bug was in effect:

import { AuditLogEvent, Guild } from "discord.js";

declare const guild: Guild;
const auditLog = await guild.fetchAuditLogs().then(({ entries }) => entries.first()!);

// We didn't specify a specific type to fetch. Therefore, it could be anything.
if (auditLog.action === AuditLogEvent.BotAdd) {
  // never
}

Status and versioning classification:

• Code changes have been tested against the Discord API, or there are no code changes
• I know how to update typings and have done so, or typings don't need updating
