Reproduction

https://github.com/drevantonder/form-actions-nuxt-dynamic-param-repro

1. pnpm i
2. pnpm run dev
3. Open up in browser
4. Try "Nuxt Param" page (/param/nuxt-param)... Doesn't work.
5. Try "H3 Param" page (/param/h3-param)... It works.

Describe the bug

It may not necessarily be a bug, but it is confusing due to the lacking documentation.

When trying to set up a form action for a Nuxt page with a dynamic parameter (e.g. pages/[param]/nuxt-param.vue) creating an action matching the Nuxt path (e.g. server/actions/[param]/nuxt-param.vue) does not work.

Rather, after digging through .nuxt/dev/index.js, I could determine that it was h3/radix underneath the hood that the path needed to match not Nuxt. So to match a path with a dynamic parameter, the :param syntax needed to be used rather than [param].

Would be good to either support the same syntax as the pages, server/routes and server/api folders, or document the difference.
