Add support for tabs

[wermos]

I want to add something like the tabs in this page: https://keqingmains.com/hu-tao/#Artifact_Sets and be able to make it look the way I want. I found a Jekyll plugin for tabs, but the CSS is underwhelming.

I will probably need to integrate Tailwind or Bootstrap with Jekyll in order to make the tabs look really nice. I will probably need Webpack for Tailwind, but I don't know how to add Bootstrap. I need to investigate this further.
