docs: update calculator example description (modelcontextprotocol#115)

look · web-flow · commit dffae27cf0ec · 2025-04-10T20:04:15.000+08:00
The example in the README uses "sum" for both `sum` and `sub`. I changed it to "difference". For consistency, I also updated the example code to use the same term.
