The NetBSD job failed when installing git on a fresh runner, because the
image ships pcre2-10.48 and the git package needs pcre2>=10.48nb1, and
pkg_add does not update installed dependencies by default.
Pass -uu to pkg_add so it also updates installed dependencies that are
too old. Also drop the PKG_PATH override. netbsd-vm now writes the live
package mirrors for the running release to /etc/pkg_install.conf, so the
override is no longer needed to avoid the image's 9.0 fallback.
