"edge" runtime is not allowed in pages router getServerSideProps. "experimental-edge" is forced though it shouldn't be.

To Reproduce

1. pnpm build

Current vs. Expected behavior

Current:

Error: Page / provided runtime 'edge', the edge runtime for rendering is currently experimental. Use runtime 'experimental-edge' instead.

Expected:

While changing the runtime to experimental-edge does work, but edge should work too. The documentation says so, hence either the documentation is wrong or the error should not be thrown. Since the edge runtime has been stable for a long time now, I think the bug is more in the code than in the documentation.
