Workaround: do not run paket install or update

The first error can be worked around fairly easily, by replacing ASCII.bytes "refreshed" with ASCII.bytes "refreshed" |> ByteSegment in build.fsx.

However after updating build.fsx to use the modern FAKE libraries, I start hitting problems - I'm guessing due to older FSharp.Literate or FSharp.Formatting etc. versions. Currently stuck on this:

System.TypeInitializationException: The type initializer for '<StartupCode$FSharp-Formatting-Common>.$YaafFSharpScripting' threw an exception. ---> System.TypeLoadException: Could not load type 'FSharp.Compiler.SourceCodeServices.FSharpChecker' from assembly 'FSharp.Compiler.Service, Version=25.0.1.0, Culture=neutral, PublicKeyToken=null'.
