Double-check GraalVM support

[jbartok]

Did reopen it and started working on GraalVM support in the plugin, but found another issue: foojayio/discoapi#66

I'll continue when they fix it (almost finished).

[jbartok]

Done.

@sschuberth something is not right with the GraalVM support. When you attempt to fetch packages for those distributions you just get a huge list of packages from other distributions. Try for example:

curl -X 'GET' 'https://api.foojay.io/disco/v3.0/packages?version=11&distro=Graal+VM+CE+11&latest=available&directly_downloadable=true&package_type=jdk' -H 'accept: application/json'

@jbartok that query of yours is using the wrong name for the distro, which is what I was trying to hint at initially. However, also https://api.foojay.io/disco/v3.0/packages?distro=graalvm_ce11 does not work, though in a different way: It says "No package(s) found". I've asked about that.

[jbartok]

It's not the wrong name per se, but it's the name and not the api_parameter value, which is maybe what I should be using. Also asked them, let's see what they come back with. Thanks!

Can we reopen this now that foojayio/discoapi#51 was fixed and add GraalVM support to the plugin @jbartok?
