In microsoft/vcpkg#37563 (comment) we have an example of versions which meet the semantic versioning format but don't sort like semantic versions, so the message:

```console
PS D:\vcpkg> .\vcpkg.exe x-add-version sqlite-modern-cpp
Use the version scheme "version" rather than "version-string" in port "sqlite-modern-cpp".
Use --skip-version-format-check to disable this check.
```

is too strong. We need to explain to the user that they should only do that if the versions actually are intended to sort that way.

…e reader is familiar with semantic verisoning rules.
