pybind#6089 dropped the coding cookie prepended to py::eval/py::exec source, which had shifted reported SyntaxError and traceback line numbers by one, and noted that no test asserted on them. Add one: errors on line 2 of the evaluated source must report line 2. With pybind11's own test target the new test reports (3, 3) against the parent of pybind#6089 and (2, 2) with the fix.

Description
Adds regression coverage for #6089: a
SyntaxErrorand an exception traceback originating on line 2 of evaluated source must both report line 2.Checked with pybind11's own test target (
PYBIND11_TEST_OVERRIDE=test_eval.cpp, CPython 3.12.13, macOS arm64, Apple clang 21):test_evalpasses at current master, and witheval.hfromf00aa6fe(the parent of #6089) only the new test fails, reporting(3, 3).
