fix: re-export more types from @sapphire/pieces

[favna]

Some of these really should've always been there (like AliesPieceJSON and PieceJSON) but I noticed this when trying to import StoreRegistryValue which is the type of store in:

for (const store of this.container.stores.values()) {

}

so previously you couldn't pass store into a receiver function as happens in sapphiredev/examples without adding an import from @sapphire/pieces when for all other purposes you only need to import from @sapphire/framework.
