version: show only the libpsl version, not its dependencies

The libpsl version output otherwise also includes version number for its
dependencies, like IDN lib, but since libcurl does not use libpsl's IDN
functionality those components are not important.

Ref: https://github.com/curl/curl-for-win/issues/63
Closes #12700
