Previously variable declaration required a keyword, e.g. ```kcl let x = 4 const x = 4 var x = 4 ``` These were all valid, and did the exact same thing. As of this PR, they're all still valid, but the KCL formatter will change them all to just: ```kcl x = 4 ``` which is the new preferred way to declare a constant. But the formatter will remove the var/let/const keywords. Closes https://github.com/KittyCAD/modeling-app/issues/3985

fn decagon = (radius) => {
step = 1 / 10 * tau()
sketch001 = startSketchAt([cos(0) * radius, sin(0) * radius])
return reduce([1, 2, 3, 4, 5, 6, 7, 8, 9, 10], sketch001, (i, sg) => {
x = cos(step * i) * radius
y = sin(step * i) * radius
return lineTo([x, y], sg)
})
}
