[javascript] What does 'x packages are looking for funding' mean when running `npm install`?

npm decided to add a new command: npm fund that will provide more visibility to npm users on what dependencies are actively looking for ways to fund their work.

npm install will also show a single message at the end in order to let user aware that dependencies are looking for funding, it looks like this:

$ npm install
packages are looking for funding.
run `npm fund` for details.

Running npm fund <package> will open the url listed for that given package right in your browser.
