Download protoc zip: Warnings/blocks from chrome and macOS Sonoma

[joelavan]

chrome 123.0.6312.87, macOS Sonoma14.4.1, M1

Repro:
Using chrome, download protoc-26.1-osx-universal_binary.zip

• Notice chrome warning: "This file is not commonly downloaded and may be dangerous."
  Select keep:
• Chrome warning: "Even if you have downloaded files from this site before, the site may be temporarily unsafe (hacked). Try downloading this file later."
  Select keep
  Unzip and attempt to run protoc
• macOS warning: "protoc" can't be opened because Apple cannot check it for malicious software. This software needs to be updated. Contact the developer for more information."

I bypassed all this by downloading via curl: curl -0L https://github.com/protocolbuffers/protobuf/releases/download/v26.1/protoc-26.1-osx-universal_binary.zip --output protoc-26.1-osx-universal_binary.zip

similar to this issue with grpc:
grpc/grpc-web#650

Didn't see this while searching for issues, so logging it now. Even if the advice is similar to the grpc issue and use curl or some other method, figured I'd log it so others my find and unblock themselves.
