runner 2.309.0 apparently runs on mac-10.13, but includes incompatible node binary

[chickenandpork]

Describe the bug
The runner claims compatibility with MacOS-10.13 and later. The tarball seems to include a node binary that doesn't share the same compatibility with macos-10.13.

To Reproduce
Steps to reproduce the behavior:

1. go into a Mac OS intel box running 10.13 (latest is 10.13.6 in that line)
2. install normally: unpack, ./config.sh, ./run.sh
3. Use this runner in a build
4. Witness the error in the node binary (failed after 7 seconds, this is the first line of the build output):

dyld: lazy symbol binding failed: Symbol not found: ____chkstk_darwin
  Referenced from: /usr/local/actions-runner/externals/node20/bin/node (which was built for Mac OS X 10.15)
  Expected in: /usr/lib/libSystem.B.dylib

The part that makes me super-accusatory is "was built for Mac OS X 10.15", which may imply "won't work in the 10.13 that runner seems to support"

Expected behavior
Expected typical build job: build is picked up, built, happily completed.

Runner Version and Platform

runner-2.309.0

OS of the machine running the runner? OSX/Windows/Linux/...
intel mac (Macmini5,3) running macOS 10.13.6 (17G14042)

What's not working?

It seems though the work is done via a node v20 process included in the runner archive; this node binary does not support Mac-10.13, which seems an oversight: Runner claims to support macOS-10.13.

Hey @chickenandpork, in order to evolve the security of the Actions ecoysystem, we are moving towards node 20. Node16 has reached the end of its life. You can read about that effort here. Sadly High Sierra does not support node 20, and is no longer supported by Apple. We have a planned date to disable Node 16 in Spring of 2024, we would strongly encourage you to update your macos version before that time.

For now, reverting to the v3 version of checkout should solve your issue, as v4 is node20.
