fix(#40025): run `next/script` beforeInteractive test in both dev & prod (#40541)
Ref: #40002 #40026 #40191
Fixes #40025
This is the final step of fixing #40025. The PR migrates the rest of the
`next/script` test cases to run in both dev (strict mode) and
production, confirming that the `next/script` component is now
completely concurrent rendering resilient and is ready for the upcoming
React 18 `<OffScreen />`.
