GitHub Actions Windows Coverage build on is broken

[richardlau]

The Coverage Windows workflow on GitHub Actions is failing on main.

e.g. for 4f5d11e:
https://github.com/nodejs/node/actions/runs/16752649115/job/47426712106#step:6:6232

  In file included from src\quic\data.cc:4:

AFAIK the Jenkins CI on Windows is passing, so I assume this is compiler level related?

Ugh. Yeah, likely compiler related. I can revert that part of the change shortly. Will open a PR later today
