Fix `curl_easy_setopt()` parameter type problem, again (#5858)

As of three weeks ago, every CI build of Git for Windows' ARM64 flavor
of its SDK started failing (the first failed build is this
[here](https://github.com/git-for-windows/git-sdk-arm64/actions/runs/17633130672/job/50104373185)).

I had mistaken this for a problem with `git/git` and therefore tried to
fast-track (for some definition of "fast") the patch into `git/git`, but
I had forgotten that I changed `git-sdk-arm64`'s `ci-artifacts` workflow
[to build `git-for-windows/git`
instead](https://github.com/git-for-windows/git-sdk-arm64/commit/1b7ec02e29ae3638cf93b603ad2f9a2248b0e85e)
(because of the problems that needed to be fixed).

So let's integrate these patches into Git for Windows before they
trickle in via a new Git version (which is [currently scheduled for
November 17th, 2025](https://gh.io/gitCal)).

This is a companion of https://github.com/gitgitgadget/git/pull/1974.
