Attach self-contained binaries to releases

[JamieMagee]

Right now, our releases contain a tarball of the source code at the particular tag, but we should also be building and attaching platform specific binaries to each release.

.NET is able to compile self-contained, platform specific, releases using dotnet publish --self-contained --runtime <win-x64|linux-arm64|...>. These binaries are independent of any .NET runtime deployed on the host machine.
