Rename `term` into `value` in `Tuple.insert_at`
Rename `term` into `value` in `Tuple.insert_at`

In `Tuple.insert_at` documentation, a variable `value` was used
to represent a value to be inserted into a tuple. In the function
definition, however, it was represented as a variable `term`, which
was inconsistency and apparently a typo.
