"Find Usages" sends incorrect line number to `textDocument/references` on decorated function in python

steps to reproduce

1. clone my test repo at https://github.com/DetachHead/test/commit/9e5a8fe2d6e53e18cee73547f8bdce1536a6ab68
2. run ./pw uv sync (installs basedpyright)
3. install the pyright for pycharm plugin
4. create a python file with the following contents:

   def foo[T](fn: T) -> T: ...
   
   
   @foo
   def bar(): ...
   

5. right click bar and click "Find Usages"

actual result

it shows usages of foo instead:

this is because the request is sending line 3 & character 1:

i assume it's not accounting for the decorators when determining where the function name is located.

expected result

when doing the same thing in vscode, it correctly sends line 4 & character 5:

Start by reproducing the decorated-function case from the linked test repository and inspect the Find Usages request sent to textDocument/references. Trace the request construction in the Java LSP client, comparing the reported line and character with the working VS Code request; done means the request targets bar rather than foo.
