Fix banned words check and update dts-critic

[sandersn]

1. Update to dts-critic 1.2, which no longer requires project urls to include the homepage url specified on npm.
2. Check for banned words for all packages, not just those complex enough to have a package.json. The location of the check was wrong.

I'm not familiar with the “download” rule. Have you seen this? https://github.com/npm/validate-npm-package-name

It doesn't test against npm's spam filter :(

> var v = require('validate-npm-package-name')
undefined
> v('download-file-async')
{ validForNewPackages: true, validForOldPackages: true }

I opened npm/validate-npm-package-name#23, but I'm not holding my breath because it hasn't published an update in 2 years, and @brettz9 opened a PR two months ago that hasn't been looked at.
