add Context.setExecutionContextFromCommandLineArgs

[cataggar]

This moves this boilerplate into a function. A minimal build script that works on .NET 6 & .NET 7 with Visual Studio IntelliSense and works with private NuGet feeds will now be:

#!/usr/bin/env -S dotnet fsi
#r "nuget: Fake.Core.Target"

Fake.Core.Context.setExecutionContextFromCommandLineArgs __SOURCE_FILE__

open Fake.Core

Target.create "clean" (fun _ ->
  Trace.log "Cleaning stuff"
)

Target.create "build" (fun _ ->
  Trace.log "Building the app"
)

Target.create "deploy" (fun _ ->
  Trace.log "Deploying app"
)

open Fake.Core.TargetOperators

"clean"
  ==> "build"
  ==> "deploy"

Target.runOrList()

This can be run with dotnet fsi build.fsx. On Linux or Mac OSX, this can be run with ./buid.fsx as well.

What if executed not from the script?

Maybe it must be in the separate package?

Will we add the line about this to the release notes?

Looks like the build failures for this one are because Fantomas wants the code to be formatted
