Allow build without env variables

[Byteingpython]

Is your feature request related to a problem? Please describe.
Noodle is in its current state noy able to be shipped in any prebuilt form (e.g. Docker Container) Because the Environment variables are needed for the build.

Describe the solution you'd like
A way to only provide those env Variables at runtime

Describe alternatives you've considered
Dont ship any prebuilds

I actually disagree with this because of a few reasons:

• without the build failure due to missing environment variables, noodle will not work as intended at all. it won't be able to connect to a db or provide authentication.
• A docker image for Noodle should have the capabilities of providing these environment variables in the image's config (like how the Postgres image works for example) and it should fail if these aren't provided as well.

I know it might be a pain at first, but it ensures that the application will work as intended and t3-env is a great package.
