During install or sync ctrl+c only cancels single package installation #169

While running poetry install or poetry sync on macOS, ctrl + c will only cancel the installation of the current package being installed. This can be an issue for projects with a longer list of packages if you want to cancel the entire installation.

Won't assume but I would personally prefer to cancel the entire installation process vs stopping (skipping?) a single installation by inputting ctrl + c at the right time. Instead expecting skipping of a single(s) installation using the grouping and the --only or --with functionality.

Noting that this issue existed in poetry's old repo but was listed for windows, so this might not be platform specific.

platform: macOS sequoia 15.7.4
poetry ver: 2.3.3
python ver: have experienced this against 3.10.13 and 3.12.13)
