Load the OpenFGA server config file into a table and show corresponding env variables

[rhamzeh]

We should be able to dynamically map the config file on the OpenFGA to the corresponding env variables to mae it easier for users.

We can do this at build time as a first step, with the caveat that it will be out of date if changed until the next merge to main of the docs.

After we can use js (if enabled) on the frontend to update it with the latest available.

As an example of what it might look like, Navidrome docs have a nice table for that. We can do something similar.

What we don't want to do is ask developers to update the docs after they have updated the code, because even with a strict review process, it is very likely these will end up out of date.
