core.addPath() can break $PATH in the openSUSE container

[ueokande]

Describe the bug

When I use core.addPath() in the openSUSE container, it breaks $PATH in the container and any command fails with the following error:

OCI runtime exec failed: exec failed: unable to start container process: exec: "sh": executable file not found in $PATH: unknown

Here is a minimal reproduction repository: https://github.com/ueokande/actions-add-path. The action script calls core.addPath() with the custom path. The GitHub Action manifest to reproduce the error is the following:

name: 'ci'
on:
  push:

jobs:
  test:
    strategy:
      fail-fast: false
      matrix:
        container:
          - fedora
          - debian
          - opensuse/leap
    runs-on: ubuntu-latest
    container: ${{ matrix.container }}
    steps:
      - run: id
      - uses: ueokande/actions-add-path@master
      - run: id

It works as expected in the Fedora and Debian containers, but openSUSE does not work.

Expected behavior
The core.addPath() should work in the openSUSE container as other distributions.

I found that this issue is caused by the runner agent. I've reported actions/runner#3210 and close this issue. Thank you.
