Merge branch 'release/5.2.0' into master

OnTopic Editor 5.2.0 is a very minor update, which doesn't introduce any new public-facing features, but does make a number of performance improvements, such as reducing the amount of mapping that needs to be performed for each topic by relying on the new lightweight `PermittedContentType` view model (#50) and supporting the new `AttributeDictionary` constructor for view models (#49). In addition, it also includes a number of internal code improvements, such as adoption of new C# 10 capabilities (#52), including global using directives (#53).

See Pull Request #57 for details.
