Specify a version for rapids_logger dependency (rapidsai#17573)

## Description
rapidsai#17307 broke builds that use the rapids-cmake pinned dependencies
feature since no version was specified for the rapids_logger dependency.
This adds a version string equal to the git tag so the dependency has a
stated version.
