Documentation: Auto-generate a structures reference?

I've been rummaging around the ts-morph.com website for months, and I just keep wanting to see a reference directory on the structures ts-morph uses. Say, at `docs/references/structures`, I would like to see a list of fields on the structures at a glance, with hyperlinks to other structures which each field references.

This might also be a good use case for dogfooding ts-morph: using it to scan its own source code after a build, in [packages/ts-morph/src/structures](https://github.com/dsherret/ts-morph/tree/latest/packages/ts-morph/src/structures) to create Markdown pages.

Usually, what I end up doing is abusing Visual Studio Code with tricks like this:
```typescript
export type ResolveTypeUnion = Pick;
type A = ResolveTypeUnion;
// ^?
```

... and then hovering over "A" to see what happens. It's not very efficient.

Start by reviewing the structures in packages/ts-morph/src/structures and the existing ts-morph.com documentation layout. Define the reference format under docs/references/structures, including how fields link to referenced structures and whether generation should use ts-morph after a build. Done means the structures are discoverable with accurate fields and working hyperlinks.
