change .well-known/package.json to use the static directory

[ryanatkn]

If you link to the .well-known/package.json, SvelteKit won't see it during the build. I think the build is fine, it just fixes the error.

I knew this was the better implementation but I was being lazy, it's more work and I want to make reusable helpers for creating the file temporarily and then cleaning up.

like

const cleanup = copy_temporarily(...)

(similar usecase with "public": true and src/)

• try/catch around build to ensure cleanup
