Add donuts & nicob to about/people

I never got round to adding myself to about/people either, so let's do both at once.

@nicob, if you'd like to be added to the website (which is totally optional, but good to do if you ever engage with the wider community), could you add the following details in this ticket please? I'll do the rest.

_model: person

_hidden: yes
---
role: core
---
name: <your name goes here>
---
twitter_handle: <twitter handle goes here>
---
mastodon_url: <mastodon profile url goes here>

nickname: <your IRC handle goes here>

pronoun: <choose from list at https://pronoun.is/>
---
gpg: <pgp key goes here>

<short one sentence bio/description goes here>

Name and bio are required, but everything else is optional I believe. Please leave anything you don't need or would prefer not to include blank.

As a reminder to myself:
