Update ChessBoard.py (DhanushNehru#401)
* Update ChessBoard.py Coordinate Labels: Displays row numbers (1-8) and column letters (A-H) around the board. Dynamic Piece Placement: Pieces (e.g., rooks and pawns) are placed using Unicode chess symbols. Square Highlighting: Allows highlighting specific squares (e.g., valid moves or selected positions). * Fixes Implemented Properly handled form POST requests Created a /cloned_sites/ directory for saved pages Fixed JavaScript to properly submit the form Handled errors gracefully
