[documentation] 404s in internal documentation links

[bjrne]

Bug

What is the current behavior?
When visiting the documentation under https://mongoosejs.com/docs/api.html#mongoose_Mongoose-Document (via first Google hit to api.html and then clicking on the Mongoose.prototype.Document() link), a click on the Document link there leads to https://mongoosejs.com/api/document.html which returns a 404 when it should probably link to https://mongoosejs.com/docs/api.html#Document .

If the current behavior is a bug, please provide the steps to reproduce.
Stated above.

What is the expected behavior?
It should probably link to https://mongoosejs.com/docs/api.html#Document .

What are the versions of Node.js, Mongoose and MongoDB you are using? Note that "latest" is not a version.
There is no version number in the docs, but the docs are referring to mongoose 6.1.1
