feat: merge with explore.ipld.io repo

[SgtPooki]

With the changes in #360, we're duplicating a lot of the logic to get a good testing environment going.

We should merge the two repos (either into this repo, or into ipld/explore.ipld.io), because:

1. explore.ipld.io does not have any exports except the website. We have most of that in ipld-explorer-components with the changes in feat!: remove all old deps #360
2. Maintaining two repos seems excessive at this point
3. Exporting a library from the same repo we use to publish the component library makes using that component library mostly self documenting, instead of having it in two places (README of component library and source of explore.ipld.io)
4. vite config and devPage.jsx and vite's index.html is duplicated in both places and really shouldn't need to be.
