Which issue does this PR close?

Closes #.

Rationale for this change

This change makes the SQL and DataFrame (DF) examples at https://arrow.apache.org/datafusion/user-guide/example-usage.html more similar.
Currently the SQL example uses LIMIT 100 while the DF one collects all results and then just prints the first 100 via show_limit(100).

What changes are included in this PR?

The sample DF code now uses limit() instead of show_limit().

Are these changes tested?

No.

Are there any user-facing changes?

No
