3127. Make a Square with the Same Color Easy

1/**
2 * [3127] Make a Square with the Same Color
3 *
4 * You are given a 2D matrix grid of size 3 x 3 consisting only of characters 'B' and 'W'. Character 'W' represents the white color<!-- notionvc: 06a49cc0-a296-4bd2-9bfe-c8818edeb53a -->, and character 'B' represents the black color<!-- notionvc: 06a49cc0-a296-4bd2-9bfe-c8818edeb53a -->.
5 * Your task is to change the color of at most one cell<!-- notionvc: c04cb478-8dd5-49b1-80bb-727c6b1e0232 --> so that the matrix has a 2 x 2 square where all cells are of the same color.<!-- notionvc: adf957e1-fa0f-40e5-9a2e-933b95e276a7 -->
6 * Return true if it is possible to create a 2 x 2 square of the same color, otherwise, return false.
7 *  
8 * <style type="text/css">.grid-container {
9 *   display: grid;
10 *   grid-template-columns: 30px 30px 30px;
11 *   padding: 10px;
12 * }
13 * .grid-item {
14 *   background-color: black;
15 *   border: 1px solid gray;
16 *   height: 30px;
17 *   font-size: 30px;
18 *   text-align: center;
