Fix error report highlight for unmatched type annotation (#27195)
Summary:
This PR fixes https://github.com/pytorch/pytorch/issues/25801 (see there for my verbose analysis).
As an example, for the following code:
```
import torch
torch.jit.script
def f1(x):
# type: (int, int) -> None
pass
```
this PR will change error message from this:
```
RuntimeError:
Number of type annotations (2) did not match the number of function parameters (1):
# type: (int, int) -> None
```
to this:
```
RuntimeError:
Number of type annotations (2) did not match the number of function parameters (1):
at __scratch__/example.py:4:0
torch.jit.script
def f1(x):
~~~~~~~~ <--- HERE
# type: (int, int) -> None
pass
```
