This is a Major Version update of Ionide! The headline features for this release include
integrated support for VSCode Tasks for build actions
integrated support for VSCode Launch Configurations for debugging
Inlay Hints for types and parameter names
A new Test Explorer integration
Much improved completion support
and a host of other minor UX fixes
FsAutocomplete version 0.52.0: https://github.com/fsharp/FsAutoComplete/releases/tag/v0.52.0

This version requires .NET 6 at minimum in order to run. We made this decision because .NET 5 is going out of support in early May 2022.
