Create release.yml (#48)

* Add CI/CD workflows for release and testing

- Introduced `release.yml` for building, testing, and publishing `GeoUK` and `GeoUK.OSTN` projects to NuGet.org on release events.
- Updated `pr.yml` to include .NET setup, dependency restoration, building, and testing steps.
- Modified `GeoUK.OSTN.sln` to include the new `GeoUK.OSTN.XUnit` project and ensure proper workflow file references.

* Update release.yml to pack NuGet packages for projects

Replaced dotnet build commands with dotnet pack for the
GeoUK and GeoUK.OSTN projects in the release workflow.
This change prepares the projects for distribution by
creating NuGet packages instead of just building them.
