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`.

- ~[ ] SHA512s are updated for each updated download.~
- ~[ ] The "supports" clause reflects platforms that may be fixed by
this new version.~
- ~[ ] Any fixed [CI
baseline](https://github.com/microsoft/vcpkg/blob/master/scripts/ci.baseline.txt)
entries are removed from that file.~
- ~[ ] Any patches that are no longer applied are deleted from the
port's directory.~
- [x] The version database is fixed by rerunning `./vcpkg x-add-version
--all` and committing the result.
- [x] Only one version is added to each modified port's versions file.
