feature request: add a theme to site

Is your feature request related to a problem? Please describe. No

Describe the solution you'd like The current site is fast and it does what it needs to do: provide a place for my blog articles that are readable, but the current theme is lacking in a couple of things, namely:

It's awfully boring
It's hurting me eyes after sunset because of the light theme.
No colours whatsoever.
Did I mention it's boring?

The current theme is Mimima and it's the default theme for a Jekyll site on GitHub pages.

Describe alternatives you've considered There are a couple of themes I'm considering:

The cayman theme

This is an officially supported Github pages theme, as can be seen here: [Themes}(https://pages.github.com/themes/) It's a nice looking theme, but it doesn't have the same layouts as minima out of the box. Also, there's no link to the about page in the header.

The Dracula theme

Not officially supported, but it looks nice (to me), is dark by default and I use Dracula for VSCode and other apps as well. However, it also only has a default layout and misses the page, post and base theme that minima has.

The minima theme (latest version)

This is the theme I'm using, but the theme preview listed on the README shows a couple of added features:

An option to switch themes between light and dark and other options.
Added options in the footer for social media links and RSS feed.
