Subject: [PATCH] [DOC] Remove outdated note from WeakRef#initialize

The note

> Raises an ArgumentError if the given +orig+ is immutable, such as Symbol,
> Integer, or Float.

has not been true since #2313 (GH-2313, Feature #16035) when
@casperisfine enabled storing non-finalizable objects in the underlying
`ObjectSpace::WeakMap`.

On Ruby 2.7+, `WeakRef.new(1) + 1` works fine and the result is the
expected 2.
