Originally, this port copied the single header provided by the upstream
into the install destination. This required consumers to use the package
via `find_path(semver.hpp)`, which is less robust, is inconsistent, and
doesn't use targets.
These changes update the vcpkg port to leverage the config-file package
offered by [neargye/semver](https://github.com/Neargye/semver). With
this, consumers use the package through `find_package(neargye-semver
CONFIG), and the target `semver::semver`.
