timeline: re-export ReactionsByKeyBySender and ReactionInfo types (…

…#3787)

This tiny change allows one to easily name the return type of
`EventTimelineItem::reactions()` such that you can use it in a function
signature. Same goes for the `ReactionInfo` type.

I think this was likely just a small oversight in recent changes to the
reactions API, so hopefully it's not controversial.

Without this, it's impossible to write a function that uses
`ReactionsByKeyBySender` or `ReactionInfo` in the signature.
