KCL samples missing const keyword, don't work in Zoo Modeling App

[spoon16]

Missing const keywords from many of the code samples in the docs which means they don't work in the modeling app when copy and pasted.

For example see https://zoo.dev/docs/kcl/shell

This code (from the shell docs) doesn't work without modification when pasted into the Modeling App.

// Shell a sketch on face object on the end face.
size = 100
case = startSketchOn('XY')
  |> startProfileAt([-size, -size], %)
  |> line([2 * size, 0], %)
  |> line([0, 2 * size], %)
  |> tangentialArcTo([-size, size], %)
  |> close(%)
  |> extrude(65, %)

thing1 = startSketchOn(case, 'end')
  |> circle({
       center: [-size / 2, -size / 2],
       radius: 25
     }, %)
  |> extrude(50, %)

thing2 = startSketchOn(case, 'end')
  |> circle({
       center: [size / 2, -size / 2],
       radius: 25
     }, %)
  |> extrude(50, %)

// We put "thing1" in the shell function to shell the end face of the object.
shell({ faces: ['end'], thickness: 5 }, thing1)

Thanks for filing @spoon16, we recently made those keywords optional in this PR but should have done a new version release of the app before we updated the docs! We're working to release v0.25.6 now, which once you receive that auto-update should allow you to use these new iterations of the KCL samples (and we actually added a command to be able to import samples directly without having to copy/paste).
