Bug #9701: RDoc description for `String#<<` and `String#concat`

As far as I can see, String#<< is an alias of String#concat, but in the RDoc, there is no mentioning of the connection between them. String#<< should be simply described as an alias of String#concat.

[srawlins (Sam Rawlins)]

True story, in string.c:

rb_define_method(rb_cString, "concat", rb_str_concat, 1);
rb_define_method(rb_cString, "<<", rb_str_concat, 1);

Closing, because:

• in 2.1, 2.2, 2.3, the example code shows uses of both #<< and #concat,
• since 2.4, they are not aliases any more (#concat now accepts multiple arguments).
