Fix #104698: Assert and failure adding shortcuts to curves sculpt tools

The keymap name in `WM_keymap_guess_from_context` didn't match the
name of the keymap in the Blender default keymap (`km_sculpt_curves`).
Fix by changing the utility function to match the keymap name.

Before right clicking on any tool in curves sculpt mode gave an assert,
now it shows a context menu.
