have something like ${files} that would list the updated files and output something like this: "Body.jsx, Navbar.jsx, Footer.jsx"
maybe have some params to limit the number of files, something like ${files:3} which would output "Body.jsx, Navbar.jsx, Footer.jsx and 7 other files", or another example ${files:1} to output "Body.jsx and 9 other files"
possible usage "Modified ${files:3} that are new" to output "Modified Body.jsx, Navbar.jsx, Footer.jsx and 7 other files that are new"
