Remove unpurpose test

[huozhi]

The test from #31784 can pass with or without the source code change in that PR.
I cannot repro it. The writable is true on build in the provided case

[awareness481]

My intention was for it to act for a regression test but it's highly unlikely the bug gets reintroduced in the same the manner (imo).

@awareness481 Thanks for the explanation, I think would be great if we can find any case that repro that issue and convert it to a test case.

@awareness481 Thanks for the explanation, I think would be great if we can find any case that repro that issue and convert it to a test case.

Oh my bad, I didn't see that you said that you can't repro without the merged PR. I only tried a couple Next.js versions just now and I couldn't reproduce, I'll try to investigate more when I have more free time.

In the meantime, FWIW I agree the the test should be removed (and possibly the original PR should be reverted?).

Edit: Right now I can only reproduce with next-boost as the original comment suggests

Tried 12.0.4 & 12.0.5-canary.9 on this repo and the issue was reproduced. I distinctly remember being able to reproduce without next-boost but it's been three months since the PR and I could have also been mistaken.
