Fix mismatched customer count in CLV Quickstart guide

[takechanman1228]

Overview

This Pull Request corrects a discrepancy in the CLV quickstart guide documentation. The guide currently states to look at the "five more promising customers," while the associated code snippet is actually designed to display the top four customers.

Details

The specific line in the documentation that has been updated is:

• Before: Let's look at the five more promising customers.
• After: Let's look at the four more promising customers.

The corresponding code that illustrates this operation is:

sdata.sort_values(by="expected_purchases").tail(4)

As the code correctly fetches the top four customers, no changes to the code were required—only the textual description needed to be updated to reflect the actual behavior of the code.

Additional Information

Please find attached a screenshot which demonstrates the code's output prior to the documentation correction.
