Describe the bug

refreshVersions is not able to find the latest versions of artifact in local maven repository.

1. Publish any project/library that uses maven-publish plugin to local maven repository, e.g. via ./gradlew publishToMavenLocal
2. Use it as a dependency in another project with refreshVersions, specifying the local repository via `repositories {

When trying out Niv and following the example from the readme to add GHC:

$ niv add ghc   \
    -v 8.4.3    \
    -t 'https://downloads.haskell.org/~ghc/<version>/ghc-<version>-i386-deb8-linux.tar.xz'

But instead using the latest ghc version (9.0.1 as of writing), I get the following error:

$ niv add ghc -v 9.0.1 -t 'https://downloads.haskell.org/~ghc/<version>/ghc-<versi

We should update the project to Java 17.
