Add a basic styled-components injection

I've never written this sort of code before but I was able to get this to work
with the help of copy and paste and using nvim-treesitter/playground.

I had a hard time trying to understand how to indent this style of code so I let
vim do it with `=` and 2 spaces seems to match other files I looked at.

This works for a basic example, like this:

```
const Layout = styled.div`
  position: absolute;
  inset: 0;
  display: grid;
  grid-template-rows: 100px 1fr 3rem;
`
```
