Option to disable Ninja recommendation

[NiklasBuchfink]

Context

In some cases, a maintainer of a project wants to prevent contributors from adding the Ninja action:

Proposal

Add an option to disable the recommendation of Ninja for all Fink users.

As we do not yet have any app-specific options, we need to define how we integrate these (e.g. part of the inlang project?).

how about an external folder that "external parties" can store whatever they need in?

for example, fink could store external/app.fink/settings.json file in the inlang file? same applies to sherlock (cc @felix.haeberle) with a app.sherlock/settings.json file.

.
└── project.inlang/
    ├── external/
    │   ├── app.sherlock/
    │   │   └── settings.json
    │   ├── app.fink/
    │   │   └── settings.json
    │   └── plugin.i18next/
    │       └── settings.json
    └── settings.json

Pros

• lazy loading of external data (in contrast to putting all settings into inlang settings.json file)
• apps, plugins, X can save whatever they need)

Cons

• more structure in the inlang file

I like the structure 👍

cc @NilsJacobsen as we probably want to render these settings into the settings component in the future.
