🔧Set assembly file version to match nuget version (v5) (#1581)

Fixes #1557

The assembly file version was incorrectly set to the same as
`<AssemblyVersion>`, which is fixed to the major version for strong
naming.

### Changes
- Explicitly configure `<FileVersion>` to match the nuget package
version
