`manage_node_deps.py` was changed in https://chromium-review.googlesource.com/c/devtools/devtools-frontend/+/2259834 to add line endings at the end of the package.json file However, `npm run install-deps` was not rerun to add the line endings. To prevent future CLs that add deps to include the line ending changes, fix them in this CL.

Callback wrapping utility
USAGE
var wrappy = require("wrappy")
// var wrapper = wrappy(wrapperFunction)
// make sure a cb is called only once
// See also: http://npm.im/once for this specific use case
var once = wrappy(function (cb) {
var called = false
return function () {
if (called) return
called = true
return cb.apply(this, arguments)
}
})
function printBoo () {
console.log('boo')
}
// has some rando property
printBoo.iAmBooPrinter = true
var onlyPrintOnce = once(printBoo)
onlyPrintOnce() // prints 'boo'
onlyPrintOnce() // does nothing
// random property is retained!
assert.equal(onlyPrintOnce.iAmBooPrinter, true)
