fix(generator): nested route missing trailingSlash

[cain]

Fixes issue #8165

I need some help finding the root of this issue. This fix just fixes the route path when generating the route, but would be good to find out where the child route is being created and adding the trailing slash there.

Hi @manniL if I'm not mistaken, you have a good knowledge about this topic (trailing slash in Nuxt). When you have the time, could you help us with this PR? 🙇‍♂️

To summarize: using nuxt-child with the trailingSlash option results in 404 in route generation. More info and reproduction in the issue #8165.

(If my memory serves me right, this issue was not present before Nuxt 2.14).
