Describe the bug

Reproduction:

• Have two pages, each with more than 100vh width.
• Scroll down on page 1
• Navigate to page 2

Expected behavior:

• Page 2 should scroll to top

Actual behavior:

• Page 2 stays at the scroll position of page 1

The reason is that router.options.ts falsely thinks that an undefined page transition is true, meaning it HAS a transition.
https://github.com/nuxt/framework/blob/bde96947333501c22a5e981515bd27c24eb8b88f/packages/nuxt/src/pages/runtime/router.options.ts#L34

Whereas page.mjs correctly interprets an undefined transition as false.
https://github.com/nuxt/framework/blob/bde96947333501c22a5e981515bd27c24eb8b88f/packages/nuxt/src/pages/runtime/page.ts#L46

I will submit a PR to fix this issue.
