chore: remove unneeded prettier eslint plugin

Issue
=====

Prettier rules seem to be enforced both via prettier itself, and in addition by eslint via
eslint-plugin-prettier.

Prettier docs state the following recommendation:

> When searching for both Prettier and your linter on the Internet you’ll probably find more related
> projects. These are generally not recommended[...]
>
> By running Prettier inside your linters, you didn’t have to set up any new infrastructure and you
> could re-use your editor integrations for the linters.
> But these days you can run `prettier --check .` and most editors have Prettier support.
>
> The downsides of those plugins are:
>
> - You end up with a lot of red squiggly lines in your editor, which gets annoying. Prettier is
>   supposed to make you forget about formatting – and not be in your face about it!
>
> https://prettier.io/docs/en/integrating-with-linters.html

Solution
========

Remove eslint-plugin-prettier from the project, and continue to use prettier as a standalone tool.
This removes the red squiggly lines in the editor.
