I used [typos](https://github.com/crate-ci/typos/).
I manually checked all the corrections and they seem safe to me.
There are still some left, but those in this PR are good
* `export env` is not in nushell
using `load-env` and `export-env` since we are `use`-ing init.nu
* reformatted export-env part to move this along
