`tools` package is deprecated. Migrate to `cmdline-tools`

[drawers]

The tools package is deprecated:

https://developer.android.com/tools#tools-sdk

I didn't spend a long time investigating, but it seems like Google has stopped serving the sdkmanager tools package this morning.

Leading to:

Warning: Failed to find package 'tools'

If it is indeed the case that tools is no longer being served, then this repo can change this:

  packages:
    description: 'Additional packages to install'
    required: false
    default: 'tools platform-tools'

to the following:

  packages:
    description: 'Additional packages to install'
    required: false
    default: 'cmdline-tools platform-tools'

And rename references in the documentation. I am not sure if this is a breaking change or not (that would require a v5).
Consumers might be looking for tools and have to migrate.

If people are stuck in the meantime while this issue is fixed, they can do (in their Android repos):

    - name: Android SDK setup
      uses: android-actions/setup-android@v4
      with:
        packages: 'platform-tools'

Which will prevent the deprecated and problematic tools from being requested
