fix: support `generate`

[Jonas Thelemann]

Describe the bug

I might very well be doing something wrong, but I observe unexpected behavior when running nuxt generate on a nuxt-link-checker enabled project: all links return a 404. Even if I disable them.
Try running nuxt generate in the linked reproduction. What am I doing wrong? :0

This should hopefully be working a bit better with 2.1.7 🤞
