Add example of GraalPy to docs (#773)

* Add support for graalpy

* add graalpy test workflow

* format, lint and build

* symlink graalpy binaries names

* fix macos names for graalpy

* Don't attempt to update pip for graalpy

* Remove test schedule

* Extract common getBinaryDirectory function for PyPy and GraalPy

* Clean up and format

* Pass GitHub token to GraalPy queries

* Utilize pagination when querying GraalPy GitHub releases

* Build

* Fix lint errors

* Deal with possible multiple artifacts for a single releases

* Skip few GraalPy tests on windows - we don't have a windows release yet

* Fix GraalPy test on Mac OS

* Build

* Skip one more GraalPy test on windows

 The `python-version` input is optional. If not supplied, the action will try to resolve the version from the default `.python-version` file. If the `.python-version` file doesn't exist Python or PyPy version from the PATH will be used. The default version of Python or PyPy in PATH varies between runners and can be changed unexpectedly so we recommend always setting Python version explicitly using the `python-version` or `python-version-file` inputs.
 
 The action will first check the local [tool cache](docs/advanced-usage.md#hosted-tool-cache) for a [semver](https://github.com/npm/node-semver#versions) match. If unable to find a specific version in the tool cache, the action will attempt to download a version of Python from [GitHub Releases](https://github.com/actions/python-versions/releases) and for PyPy from the official [PyPy's dist](https://downloads.python.org/pypy/).

 ## Hosted tool cache
 
 GitHub hosted runners have a tool cache that comes with a few versions of Python + PyPy already installed. This tool cache helps speed up runs and tool setup by not requiring any new downloads. There is an environment variable called `RUNNER_TOOL_CACHE` on each runner that describes the location of the tool cache with Python and PyPy installed. `setup-python` works by taking a specific version of Python or PyPy from this tool cache and adding it to PATH.
