fix(smol): add missing file paths to inspector protocol patch

Patch 012 was missing the --- a/ and +++ b/ file path lines, causing
patch validation to fail with "Socket patch validation failed".

Added:
--- a/deps/v8/third_party/inspector_protocol/code_generator.py
+++ b/deps/v8/third_party/inspector_protocol/code_generator.py

This matches the format of all other patches in the directory.
