Proposed Changes

Fix INSTALL_K3S_PR support

The current test is wrong, as it fails if the grep for a 401 error DOES NOT match:

k3s/install.sh

Lines 490 to 491 in 4204248

	if ! echo "$pr_raw" | grep -q "Bad credentials.*401" ; then
	fatal "Installing PR builds requires GITHUB_TOKEN with k3s-io/k3s repo permissions"
