Added support for .NET 6 to Optimizely Content Manager package of Optimizely Content Cloud (CMS).

There are no changes to the .NET 5 support, and the packages include assemblies built for both .NET 5 and .NET 6.

[Content Manager/Grid View] Fixed an unhandled exception (MissingMethodException) that was occurring after accessing Edit view.

This version of Content Manager Labs is compatible with Block Enhancements Labs version 0.10.0, which in turn is compatible with CMS UI 11.32.0. This CMS UI version contains inline edit functionality which was moved from the Block Enhancements Labs.
