Incorrect references in "Objects" section of README.md in examples

If you look at the file `README.md` file in https://github.com/adobe/jsonschema2md/blob/master/examples/docs/README.md you will see in the Objects section references to `Simple` that look like this:
```markdown
- [Simple](./complex-properties-simple.md "This is a very simple example of a JSON schema") – `https://example.com/schemas/simple#/properties/refnamed`
- [Simple](./complex-properties-simple-1.md "This is a very simple example of a JSON schema") – `https://example.com/schemas/simple#/properties/refrefed`
- [Simple](./complex-properties-refobj-properties-simple.md "This is a very simple example of a JSON schema") – `https://example.com/schemas/simple#/properties/refobj/properties/foo`
- [Simple](./complex-properties-refnestedobj-properties-refobj-properties-simple.md "This is a very simple example of a JSON schema") – `https://example.com/schemas/simple#/properties/refnestedobj/properties/refobj/properties/foo`
```
The last link works fine as the file `./complex-properties-refnestedobj-properties-refobj-properties-simple.md` is generated. But the first 3 links don't work as the 3 files reference there, `./complex-properties-simple.md`, `./complex-properties-simple-1.md` and `./complex-properties-refobj-properties-simple.md` do not exist and are not generated.

I'm not sure if the links are wrong, or if the files were not generated, but either way, something is wrong.

Start with examples/docs/README.md and compare the three broken links with the generated example files named in the issue, including complex-properties-refnestedobj-properties-refobj-properties-simple.md. Trace the examples documentation generation entry point to determine whether the links or generation output is incorrect. Done means the Objects section contains only links to files that are generated and resolve correctly.
