`:skip_undefined_reference_warnings_on` with modules in pages

[whatyouhide]

I have an extra page, say pages/my-page.md. In it, I mention MyModule, which is now a private module.

I don't want to warn on it. If I pass

skip_undefined_reference_warnings_on: ["MyModule"]

I still get the warning. The only way I found to silence it is to pass "pages/my-page.md" altogether, which is not what I want because it silences all warnings. When I inspected ex_doc, the config.id and config.module_id were both nil.

This might be a documentation problem, or a missing feature, or a bug. Not really sure. I'd love to help out more but I’m a lacking time at the moment 😉

Yeah we can silence warnings on a given page which is useful for pages with deprecations like CHANGELOG.md. At the moment we cannot silence particular warnings. I think it might be a useful feature to have. Or, you know, we should be more intentional when we want things to auto link and when we don't (#1663). :)

A PR to add skip_code_autolink_to: ["Module"] would be welcome.
