Add Scastie Box Into Artifact Page

[ayushkoli772]

With this commit I have fixed the Scastie URL according to Try library, inside Artifact.scala

I will completely fix this issue with subsequent commits

@adpi2 Please review the changes to scastieUrl so I can move forward with adding it to artifact.scala.html

Hello @adpi2, with this commit I fixed the Scastie URL and also added Scastie box

This how it looks after adding Scastie box-

And this is url you get when clicked on Try online with scastie box- https://scastie.scala-lang.org/try?g=org.typelevel&a=cats-core&v=2.8.0&o=typelevel&r=cats&t=JVM&sv=3.x

Are there any other changes you would like to suggest?
