'cp' is not recognized as an internal or external command, operable program or batch file.

I have seen that during the Chart.js building, the cp *nix command is invoked:

Chart.js/package.json

Lines 57 to 58 in 64a0278

	"emitDeclarations": "tsc --emitDeclarationOnly && cp -R ./src/types/ ./dist/types/",
	"build": "rollup -c && pnpm emitDeclarations",

In the contributing section, I don't find that the contributors should use *nix OS therefore who is working on Windows (i.e.) will get the error mentioned a discussion titile.

I didn't sumit an issue because I don't know if this is just a missing doc (contributors must use *nix OS) or an error (to fix) in package.json file.

Its an oversight, so should file a bug. I was about to move this, but can't on mobile.
