Log "Kill entire process tree" does not match actual behavior

[carlcsaposs-canonical]

I have no experience with .NET, so I apologize if I am misunderstanding and this is not a bug

Describe the bug
The log "Kill entire process tree..."

runner/src/Runner.Sdk/ProcessInvoker.cs

Line 463 in 3f28dd8

Trace.Info("Kill entire process tree since both cancel and terminate signal has been ignored by the target process.");

does not match the actual behavior of the runner:

runner/src/Runner.Sdk/ProcessInvoker.cs

Line 861 in 3f28dd8

_proc?.Kill();

.Kill(), from my understanding, only kills that process. It does not kill children processes. To kill the entire process tree, use .Kill(true)

To Reproduce
Look at source code or run job with

steps:
   - run: sleep 360
     timeout-minutes: 1

and look at logs in ~/actions-runner/_diag/Worker_*.log

Expected behavior
Log says "Kill process" instead of "Kill entire process tree"

Runner Version and Platform

Version of your runner? v2.317.0

OS of the machine running the runner? Ubuntu 22.04

What's not working?
