remove obtuse section about "bundled bind parameters"

Just looking for basics on insert in the first pages
of the tutorial I see this weird detour into something that
nobody ever uses and definitely isn't going to make sense
to the people I see complaining about our docs on twitter,
remove this.   the tutorial probably needs a big sweep
for wordy obtuse things.  the userbase is changing and
we really have a lot of brand-new-to-programming types coming
in.

-The two previous cases illustrate a series of parameters being passed to
-accompany a SQL statement.    For single-parameter statement executions,
-SQLAlchemy's use of parameters is in fact more often than not done by
-**bundling** the parameters with the statement itself, which is a primary
-feature of the SQL Expression Language and makes for queries that can be
-composed naturally while still making use of parameterization in all cases.
-This concept will be discussed in much more detail in the sections that follow;
-for a brief preview, the :func:`_sql.text` construct itself being part of the
-SQL Expression Language supports this feature by using the
-:meth:`_sql.TextClause.bindparams` method; this is a :term:`generative` method that
-returns a new copy of the SQL construct with additional state added, in this
