Move outer assets to inner organization

There are several files in the root of the repo that look like they could be scoped into their own folder (such as styles?)

These include...

https://github.com/catalystneuro/format-support-table/blob/main/create.js

https://github.com/catalystneuro/format-support-table/blob/main/index.html

https://github.com/catalystneuro/format-support-table/blob/main/open.svg

https://github.com/catalystneuro/format-support-table/blob/main/style.css

There are a wide variety of different structures that people use to organize their files using Vite—though the index.html file is (almost) always at the root of the repo.

The current system is used for the Vite Vanilla demo, whereas a src-scoped system is used for the Vanilla TS demo.

In the related PR, I've opted for the latter.

Let me know if you'd prefer anything in a different place. At the end of the day, this choice is relatively arbitrary—except for changing the location of the index.html file, which would require significant changes to the configuration.

The index part makes a bit more sense; the PR does clean the rest up more nicely
