add environment variable validation

[stefanprobst]

use @t3-oss/env-nuxt for environment variable validation with zod.

we had this before but have removed it in #5 until outstanding upstream issues are solved.

Arriving here after unsuccessfully trying to debug env variables not getting set in my app for the longest time and wondering why we use a different setup than what's described in the Nuxt3 docs...

Hmm, the linked PR was closed, not merged, though?

I was going to adapt my settings to what's in the PR so I can be done with this for the moment. :P

#5 has been merged even though github pretends otherwise.

why we use a different setup than what's described in the Nuxt3 docs

because the default setup does not validate anything

I figured it out – the PR was actually not merged, the changes were directly committed to the main branch instead. (Which made the PR superfluous, I guess!)

Gotcha, thx.
