The Kong semgrep action spins up a fresh Python 3.12 via setup-python, so the previous `pip install setuptools` ran on an unrelated Python and the action still failed with ModuleNotFoundError: pkg_resources. Call setup-python with the same pinned version first so setuptools lands in the toolcache the action reuses.
The Kong public-shared-actions/semgrep action calls setup-python@v6 with python-version 3.12 and then pip installs semgrep. semgrep pulls in opentelemetry-instrumentation 0.46b0, which imports pkg_resources at load time - but Python 3.12 no longer ships setuptools by default, so semgrep ci crashes with ModuleNotFoundError. Replace the shared action with the same composite steps so we can pip install setuptools alongside semgrep. The artifact upload and SARIF upload steps are preserved with the same pinned SHAs as before.
setuptools 81 removed the pkg_resources module, but opentelemetry-instrumentation (a semgrep transitive dep) still imports it at load time. The previous attempt installed setuptools-82.0.1, which has no pkg_resources, so semgrep ci still crashed with ModuleNotFoundError. Pin to the pre-removal series.
Revert the inline rewrite and keep using the Kong shared semgrep action. The real fix is the setuptools version: 3.12 no longer bundles pkg_resources, and setuptools >=81 dropped the module entirely, so we must seed the toolcache with setuptools<81 before the action reuses Python 3.12.
