[Feature] Add schema properties to models

[SferaDev]

In metadata-sync we use a lot displayName and sometimes plural or collectionName from the schemas. It's the last usage we rely on d2 right now. As part of one of the latest tasks we are needing displayName again and it didn't feel okay to use d2.

const foo = "dataSets";
const { displayName } = api.models[foo].schema;
console.log(displayName);

I'm not sure if we can do this using only the type, as types are not available on runtime....

It's a typical scenario, the idiomatic approach is to define the values and then derive the type:

Tested with project-monitoring-app, I can access the models info as expected. And code looks good.

The only thing that bugs me a bit is that the models is not string indexed api.models[string] even though we would require to control the not found scenario.
