Fix sbt task that creates GraalVM package (#7721)

While looking into #7698 discovered that the `buildGraalDistribution`
task would fail to use the old (pre-23.0) GraalVM naming of artifacts.
This has changed since #7176.

The fix does not attempt to fix a problem of packaged GraalVM name in
`runtime`. That, as the ticket mentiones it, is the role of rust build
script that creates the correct bundle.
