clean the package.json

[byronz]

while cleaning up the assets in both dcc and dash, we notice the package.json file in both repos might contain some deprecated/unrelated packages.

the dcc npm i time is significantly long if we can reduce that would be very helpful to reduce the CI duration too.

[alexcjohnson]

were there specific packages in dcc you flagged as possibly obsolete?

copyfiles
npm-run-all
?

[alexcjohnson]

npm-run-all provides the handy run-s, used in some of the package.json scripts.
copyfiles I don't see used though 👍
