Add GraalPy support (#694)

* 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
