Recommended folder for installing binaries

Describe the bug

The version 2.334.0 introduced the folder cs under /home/runner/bin (https://github.com/actions/runner/pull/4317).

♪ docker run -it ghcr.io/actions/actions-runner:2.334.0 ls -lash /home/runner/bin/cs/
total 40K
4.0K drwxr-xr-x  2 runner docker 4.0K Apr 21 18:50 .
 20K drwxr-xr-x 17 runner docker  20K Apr 21 18:50 ..
 16K -rwxr--r--  1 runner docker  15K Feb 13  2025 Microsoft.VisualStudio.Validation.resources.dll

Previous version, for reference:

♪ docker run --rm ghcr.io/actions/actions-runner:2.333.1 ls -la /home/runner/bin/cs/
ls: cannot access '/home/runner/bin/cs/': No such file or directory

This is a problem, for actions like scala-steward-action, more specifically due to /src/modules/coursier.ts, where it downloads Coursier and extracts under /home/runner/bin/cs but with this new version it fails due to:

gzip: /home/runner/bin/cs already exists;    not overwritten.

So, what would be the recommended fix here? Extracting under a different path (e.g., /home/runner/.local/bin/cs)?

To Reproduce

I created this repository to reproduce the issue, but since ubuntu-latest is still running 2.333.1, we cannot reproduce it yet.

Runner Version and Platform

Runner: 2.334.0
Platform: Linux (self-hosted | GKE)

Compare the contents of /home/runner/bin in the 2.334.0 and 2.333.1 images using the Docker commands shown, then read scala-steward-action's src/modules/coursier.ts extraction path. Determine which runner directory is intended for downloaded binaries without colliding with the new cs folder; done means the recommended installation path is established and the reported extraction failure is addressed.
