Hello!
We wanted to make the docs less impersonal, so we decided to add
contributors. Now each doc page that has an `editUrl` (i.e, isn't
generated) shows a list of everyone that contributed to it.
This list is generated by:
1. Running `swizzle` on the `DocItem/Footer` in Docusaurus.
2. Grabbing metadata for the current file using an internal docusaurus
API (Thank you to @homotechsual for the help there)
3. Getting the commits to the file in question with the GitHub API
<details>
<summary> Here's the command I ran, for posterity </summary>
<code>npm run swizzle @docusaurus/theme-classic DocItem/Footer --
--wrap</code>
</details>
## Discussion points
1. Design. What do you think of the layout?
2. Right now I'm hardcoding the info of Unleash team members. This
creates a small maintenance burden, but it's something we wanted to add.
We don't use the client for anything at the moment, so we can remove it.
While there are things we can use it for in the future, we should
instead add it back in when we get there.
This also removes the docs feedback form (which we haven't used since
the client stopped working)
