Automate SDK versioning in assembly

🧵 Story

The SDK is currently given its version in the assembly through the <CouchbaseNetClientReleasedVersion> property in Directory.Build.Props, which has to be modified manually before each release.

🛠️ Acceptance Criteria

The goal is to automate this, either by providing the property at build time in the appropriate CI jobs or with a tool such as GitVersion.

e.g.

dotnet build [...] --property:CouchbaseNetClientReleasedVersion=3.5.3
