Fix bundled engine after GraalVM upgrade (#9735)

The change fixes the problem with suggestions loading by
1. Making sure that bundle is always the first on the search path for editions and engine
2. Passing language home to language server

Verified by building/running AppImage locally (previously would fail).

Closes #9728. Regressed in #9647.
