Add JetBrains Runtime non-JCEF variants

[cmanto]

Currently, Foojay only indexes JetBrains Runtime packages with JCEF bundled

JetBrains also provides non-JCEF variants which are useful for:

• Development environments using jcefmaven (to avoid classpath conflicts)
• Headless environments that don't need Chromium
• Smaller download sizes

Example non-JCEF packages from JetBrains releases:

• jbr-21.0.9-osx-aarch64-b895.149.tar.gz
• jbrsdk-21.0.9-linux-x64-b895.149.tar.gz

Would it be possible to add to the index JetBrains Runtime non-JCEF variants so they're available via Gradle toolchains.

Yes that's correct because someone mentioned in the past that the only pkgs that make sense would be the ones with JCEF bundled which is the reason why we only have these pkgs. I will check your request.

Looked at it and the main problem with supporting these pkgs is that it will be hard to distinguish between the non-jcef and jcef pkgs because it is not an OpenJDK feature and we don't have a field for specific builds. For example, if you ask for a JDK from JetBrains, you cannot define if you would like to have a non-jcef or jcef build in disco. This could lead to the fact that users that would like to get the jcef variant would get the non-jcef variant and if I remember right this was also the reason why we removed them from disco.

I see, thanks for checking.
I thought there could be a JetBrainsNoCef variant but yes we need a way to tell them apart clearly
