The `newlineReporter` intends to print a new line after the test to
prevent the something print to the stdout and mess up the test result
while cause the tool like `go-junit-report` fail to parse the result.
But this is no longer needed based on following evidence.
- The issue that was first introduced in `go-junit-report` has already fixed in the version
referenced in `go.mod`.
- The `newlineReporter` report doesn't fix anything for `Ginkgo` v1 or V2 or `go test`, it just prints a
new line before the test summarization.
