strings: clarify example of ContainsAny 

I have seen code that literally copied the example like this:

    if strings.ContainsAny(s, "1 & 2 & 3") {

The developer apparently thought that this is the way to
specify multiple characters and I noticed this pattern
being used in the example. Let's update the example so
that it's clear how multiple Unicode code points should
be specified.
