Use this package to easily convert various time formats to milliseconds.

Issue

The README refers in several places to the npm package zeit/ms which does not exist in the npm registry.

ZEIT is now Vercel describes that a rebranding took place in April 2020.

The GitHub repo link https://github.com/zeit/ms redirects to https://github.com/vercel/ms

The npm registry reports not found for https://www.npmjs.com/package/zeit/ms, whereas https://www.npmjs.com/package/ms links to the current Vercel repo https://github.com/vercel/ms.

Change

Change reference to the npm package zeit/ms to ms

The hyperlink targets were already using the up-to-date location https://www.npmjs.com/package/ms. The change only affects the visible text of the corresponding hyperlinks.
