[windows-11-arm] install `zstd` for cross-OS caching

Type of issue

• Error when running a workflow.
• Request for additional tools or software for an existing image.
• Request for a new image, Linux or Windows.
• Other

Describe the issue

The windows-11-arm image is missing zstd, which is required for Cross-OS caching to work.

To Reproduce

name: Cross-OS cache

on:
  push:
  workflow_dispatch:

jobs:
  save:
    runs-on: windows-11-arm

    steps:
      - run: echo "Hello from windows-11-arm" > hello.txt

      - uses: actions/cache@v4
        id: cache-hello
        with:
          path: hello.txt
          key: hello-key
          enableCrossOsArchive: true

  restore:
    needs: [save]
    runs-on: ubuntu-latest

    steps:
      - uses: actions/cache/restore@v4
        with:
          path: hello.txt
          key: hello-key
          enableCrossOsArchive: true
          fail-on-cache-miss: true

Expected behavior

ubuntu-latest is expected to be able to restore the cache saved by windows-11-arm but cross-OS caching doesn't work due to missing zstd and it results in error:

Error: Failed to restore cache entry. Exiting as fail-on-cache-miss is set. Input key: hello-key

Additional context

See https://github.com/actions/cache?tab=readme-ov-file#usage

If you are using a self-hosted Windows runner, GNU tar and zstd are required for Cross-OS caching to work. They are also recommended to be installed in general so the performance is on par with hosted Windows runners.

Workaround

Before actions/cache:

- run: choco install zstandard
