fix(docs): correct age filtering description

[saidmtanzania]

Issue
The documentation contains an error in the description of filtering people by age. The current text incorrectly states that the filter is for people "under 18 and over 90," which contradicts the actual query logic.

Fix
Correct the description to accurately reflect the query logic, which filters out people "under 90 and over 18."

Changes Made
Updated the description to correctly state the age filtering criteria.

Before

Say you want to filter out people under 18 and over 90, but you don't want to hit the database again:

<cfquery name="filteredQuery" dbtype="query">
  SELECT     Name, Age, Location
  FROM    myQuery
  WHERE    Age >= 18
            AND Age <= 90
</cfquery>

filteredQry contains the desired records.

After

Say you want to filter out people under 90 and over 18, but you don't want to hit the database again:

<cfquery name="filteredQuery" dbtype="query">
  SELECT     Name, Age, Location
  FROM    myQuery
  WHERE    Age >= 18
            AND Age <= 90
</cfquery>

filteredQry contains the desired records.
