The `persistentMapOf` overload without arguments should be used there.
The needed overload is not available in the version of `kotlinx.immmutable 0.3.2`,
so the library is updated to the latest version.
This commit also removes the dependency on the `kotlinx-collections-immutable-metadata`
as it's not published anymore for new versions of `kotlinx-collections-immutable`.
