ci(dotnet): publish nuget packages for all supported environments (#523)

NuGet supports the distribution of native binaries. We already provide a
win-x64 package, this PR adds packages for the other environments. We
will be publishing these NuGet packages:
 - Extism.runtime.linux-arm64
 - Extism.runtime.linux-musl-arm64
 - Extism.runtime.linux-x64
 - Extism.runtime.osx-arm64
 - Extism.runtime.osx-x64
 - Extism.runtime.win-x64 (msvc)
- Extism.runtime.all -> this is a meta package that referencs all other
packages. The idea is, in the getting started guides we instruct the
user to take a dependency on `Extism.Sdk` and `Extism.runtime.all`. This
will make sure their apps work on all supported operating systems
automatically. Otherwise, they can just take a dependency on what they
care about

This PR also adds a dependency on
[MinVer](https://github.com/adamralph/minver) which make sure packages
are automatically versioned based on git tags.
