Dependency vulnerabilities

[kvo180]

I forked this repo and ran dependabot which detected a number of potential vulnerabilities with some dependencies. Most of them have newer versions that already contain patches. Can we look into updating these?

My fork for reference: https://github.com/kvo180/to-html/security/dependabot
