Login via discord / linking discord is offered despite not being configured.

[Saladoc]

Current Behavior

Despite me not configuring the discord application info, the application still offers linking discord accounts and failing with a non-userfriendly error if it is attempted.

Expected Behavior

If discord is not configured, the option to login via it should not be offered, neither should the linking of accounts.

Steps To Reproduce

1. Start without discord-specific options being configured
2. Click "link discord" button when logged in
3. Enjoy a json formatted error message.

Environment

• This happens on the official site, opentogethertube.com
• This happens using a self-hosted version.
• I'm using the docker image.

Anything else?

Just putting down my thoughts for reference later:

Fixing this is not super straight forward right now. Ideally, we should have a feature flag mechanism so we can turn off rendering for features like this. However, this would require yet another round trip call to the backend on first load with our current infrastructure (we already have 2 and that's bad enough). Maybe we could set up some minimal server-side rendering to set feature flags in a global scope?

Alternatively, we could include the feature flag in a new environment variable at build time.
