add the ability to download kind/kubectl on macOS GHA runners

[nicks]

Important note - This doesn't setup Docker on MacOS. To setup Docker, you either need to use the Docker Desktop GHA (https://github.com/docker/desktop-action), or you need to connect your MacOS runner to a remote Docker Daemon.

(I wanted to use this package to leverage kind for integration tests on Docker Desktop itself)

lgtm

can you rebase and maybe add a test case that runs on macos?

thanks for this PR and very sorry for the delay

[nicks]

added a macos test rule

@nicks the new mac testing is failing

Suggested change

	- name: Checkout
	uses: actions/checkout@b4ffde65f46336ab88eb53be808477a3936bae11 # v4.1.1

	brew install docker
	colima start

Tested this fix on my fork, it works: musse#1

Check this thread for details: actions/runner-images#17 (comment)

i don't think this is right; you shouldn't need colima running if the action is in install_only mode

[nicks]

the test failure might be revealing an existing bug in the cleanup script?

currently it always runs kind delete, even if the action has install_only set to true.

arguably, if install_only is set to true, then it's not responsible for creating a cluster, so also shouldn't be responsible for cleaning one up?

for now, i set ignore_failed_clean on the new test, which is arguably the "safest" change.
