fixup! ci: work around a problem with HTTP/2 vs libcurl v8.10.0

This was marked as a temporary work-around in 4538ee6 (ci: work
around a problem with HTTP/2 vs libcurl v8.10.0 (#5165), 2024-09-24), to
help CI builds pass even on macOS. The faulty libcurl version has hence
been replaced with plenty of fixed ones, therefore this work-around is
no longer necessary.
