Fix edge case in inductor triton clean script (#130837)

The regex in the script is too restrictive, as it excludes examples with parentheses in args, like the following:
```
triton_poi_fused_add_0.run(arg0_1.item(), arg1_1.item(), buf0, 1, grid=grid(1), stream=streamNone)
                                       ^
```
