Crawler should tell where it found link to 404 path

[issue-up]

Forwarded from downstream issue: Crawler should tell where it found link to 404 path nuxt/nuxt#8184 by @iBobik

Is your feature request related to a problem? Please describe.

In CMS there are broken links and Nuxt's crawler correctly fails when it tries to render it. But it does not tell where it found this link.

 ERROR  Error generating route "/todo": Page not found   

Describe the solution you'd like

When there is non existing path it should print a path where it found it.

Describe alternatives you've considered

Tester on a CMS side :-/
