op-deployer triggers security warning on macos

[tessr]

When I install op-deployer from the release page, macOS warns me that the software can't be verified. There isn't an obvious way to override this. I have to go into my system settings to get op-deployer to run.

I don't run into this problem when building op-deployer from source.

This is low-priority but it sure is annoying.

This happens because OSX requires all binaries to be notarized by the Apple mothership before they'll run on Mac. The workaround here is to right click on the binary, then select "Open." I'll update the docs to highlight this - there may also be a way to notarize/avoid this prompt if we use Homebrew, which I'll look into.
