Clarified collection in slice definition 

Noticed the slice definition in the first paragraph relies on the reader recalling:
* what collections are
* that the reference page ended stating slices are a kind of reference

I think the first paragraph should be more clear to someone who lands on it and isn't reading the rest of the documentation ATM.

## The Slice Type
*Slices* let you reference a contiguous sequence of elements in a collection
rather than the whole collection. A slice is a kind of reference, so it does
not have ownership.
*Slices* are a kind of reference, which lets you access a contiguous sub-sequence
of elements in a sequential [collection](book/src/ch08-00-common-collections.md).
Because slices are a kind of reference, they too can borrow access to memory, but
not own it.
Here’s a small programming problem: write a function that takes a string of
words separated by spaces and returns the first word it finds in that string.
