Host details and Scripts page: view script

[noahtalerman]

Goal

User story
As an IT admin who's about to run a script on the Host details page or who's looking at my script library on the Scripts page,
I want to to be able to quickly view the script before I run it
so that I can double check that the script is good to go.

There were a few other duplicates but I think they are all referenced in #19925 & probably closed. Thanks @noahtalerman
