Feature #16991: Sets: add Set#join

I'd like to add #join to Set:

# Now:
Set[1, 2, 3].join('x') # => NoMethodError
# After
Set[1, 2, 3].join('x') # => "1x2x3"

I'd make this join never recursive. (I've never wanted to use the recursivity of Array#join, but it may very well just be my particular experience)

Reminder: Why there is no Enumerable#join: https://bugs.ruby-lang.org/issues/1893
