Fix Incorrect Terminology and Client Count in Portal Network Documentation

[cjustinobi]

Description

Changes Proposed:

1. Diagram to Table Correction:

   • The section incorrectly refers to a "diagram" when the content is clearly structured as a table. Updated the terminology to accurately describe the content as a table.

2. Client Count Correction:

   • The documentation states that there are three Portal Network clients, but the list provided includes four clients (Trin, Fluffy, Ultralight, and Shisui). Updated the text to reflect the correct number of clients listed on the site.

Changes Made:

• Replaced "diagram" with "table" in the relevant section.
• Updated the text to state "four Portal Network clients" instead of "three."
