While applying the paper I noticed that we use the section title "Tuple interface" in [complex.tuple] and [array.tuple] instead. Shall we do the same here and rename [intseq.binding] to [intseq.tuple] along with "Tuple interface" as title?

I'm personally fine with such inconsistency because integer_sequence is not made tuple-like.

3d71a83 
Fixes NB IT 002, FR 007-011, CZ 2-143, US 78-144 (C++26 CD).

Editorial note:
* The declarations of tuple_size and tuple_element are moved to after
  the "synopsis heading" under which their specializations are
  declared, similar to how this is presented elsewhere.
