There are wrong inner links in README.md

actual:

  - [What about Web Workers?](#what-about-web-workers)

  - [How do I make the output all colorful and *pretty*?](#how-do-i-make-the-output-all-colorful-and-pretty)

  - [How do I contribute to `standard`?](#how-do-i-contribute-to-standard)

expected:

  - [What about Web Workers and Service Workers?](#what-about-web-workers-and-service-workers)

  - [How do I make the output all colorful and *pretty*?](#how-do-i-make-the-output-all-colorful-and-pretty-)

  - [How do I contribute to `standard`?](#how-do-i-contribute-to-standard-)

trailing - is required?

In GitHub, trailing - does not exist in URL.
But in standardjs.com, trailing - exists in URL. (due to difference of Markdown parser?)
