Description

When navigating on the documentation site for mongoose v5, clicking on links that lead to docs/api ignore the fact that you have v5 selected.

This problem I think is similar to the issue here #12548

Steps to Reproduce

1. navigate to https://mongoosejs.com/docs/5.x/docs/guide.html
2. click Queries under Guides.
3. Click any of the query links: for example, Model.deleteMany()

Expected Behavior

I expected v5 to stay selected. The workaround I had to do is change the url it links to, to have the base url https://mongoosejs.com/docs/5.x/docs/.
So https://mongoosejs.com/docs/api.html#model_Model.deleteMany becomes https://mongoosejs.com/docs/5.x/docs/api.html#model_Model.deleteMany. (This is mildly annoying)
