feat: Nynorsk Norwegian translation

[NeonSpork]

What does this PR do?

This PR does two things:
1 - Adds Nynorsk Norwegian translation (created nn.json, updated codes.php and init.php to reflect the addition of Nynorsk Norwegian as an option)
2 - Fixes a couple small errors in the preexisting Norwegian bokmål (no.json file) translation that were overlooked in an earlier PR (#1871).

Test Plan

Ran appwrite, followed the steps in the translation tutorial to slam out a GET request with Insomnia and got a cool 200 OK response.

You also need to check if both no.php and nn.php have been loaded in `init.php as you can see in the issue description

Yeah i added line 302 in init.php right above the preexisting no.json line to add nn.json since it was new. Was there somewhere else I was supposed to add that as well?
