PR review request: Decode subprocess output in text mode when timeout is hit

Hi everyone,

I have a bugfix PR that’s had an initial review, is passing all checks, and ready for core review: gh-87597: Decode subprocess output in text mode when timeout is hit by LewisGaul · Pull Request #95579 · python/cpython · GitHub

I opened this on 2nd August and the last activity was 15th August - would someone be able to take a look?

Thanks in advance!
