docs: Fix some small typos or "missing" docs (#1943)

* Fix documentation for GuildAuditLogEntry.target

* Update documentation for CategoryChannel#children

* Add EntryTarget for audit logs

I've done this to "fulfill" devsneks request while also showing all the possible results for the target of an AuditLogEntry

* Oops Eslint

* Private timeout sets gets set by BaseClient not WebhookClient

* Fix the "Missing Docs" for Presence#activity

* Small doc inconsistency

Array<Number> instead of Array<number> for Activity

* Client#emojis is an EmojiStore not a Collection

* Document ClientPresenceStore

Just so its clickable through the wiki, nothing else is documented

* Small fix for BaseClient#setInterval

You don't wait before executing, you execute every X ms

* GuildChannelResolvable takes a GuildChannel/Snowflake

* Typo in UserResolvable

* Another typo for UserResolvable

* Add the number to the Status and VoiceStatus docs

Its probably not needed, but just so the user knows what each number means, its now documented.
