Enable comments

[neilboyd]

It's built in as a Chirpy feature: https://github.com/cotes2020/jekyll-theme-chirpy/blob/v6.2.3/_config.yml#L81 These are the options:

• https://utteranc.es/
  • it creates issues for comments
  • user needs to sign in to github to comment
  • lightweight
• https://giscus.app/
  • a more fully-featured version of utterances
  • uses github discussions instead of issues
  • user needs to sign in to github to comment
• https://disqus.com/
  • this seems like the best option
  • the free plan is enough to start with

Will probably need moderation.
