fix(svgRenderer):update duplicate step comment in svgRenderer

[tamilr0727-ux]

Description

In src/utils/svgRenderer.ts, the section comment "STEP 1: THE GRID MAP MATRIX SYSTEM" appears twice in a row (lines ~22 and ~33), before two different blocks of code.

The second block is actually Step 2 setup work (building the gridMap dictionary), but the duplicate label makes it look like Step 1 repeats. This copy-paste mistake causes confusion and should be corrected.

Changes made

Modified the comments and followed the steps order.

Fixes #6093

Thank you for fixing this comment typo in src/utils/svgRenderer.ts! Having the steps numbered sequentially makes the rendering algorithm much easier for new contributors to understand. Approved!
