redirect from here to https://edgi-govdata-archiving.github.io/j40-cejst-2/

Redirect from this URL (https://digitalhistory.github.io/j40-pages/) to the new one (https://edgi-govdata-archiving.github.io/j40-cejst-2/) 

Updating `layout.tsx` to automatically build a redirecting `<meta>` tag on each page works, though it may not be the most efficient/correct approach:

```
<meta httpEquiv="refresh" content={`0;url=https://edgi-govdata-archiving.github.io/j40-cejst-2/`}/>
```
