workflow: test scripts flaky on macos-latest

[KevFan]

Frequently the Test Scripts (1.20.x, macos-latest) action failing due to:

Run make operator-sdk
  
./utils/install-operator-sdk.sh /Users/runner/work/kuadrant-operator/kuadrant-operator/bin/operator-sdk v1.28.1
Downloading https://github.com/operator-framework/operator-sdk/releases/download/v1.28.1/operator-sdk_darwin_amd[6](https://github.com/Kuadrant/kuadrant-operator/actions/runs/6224455726/job/16893257013?pr=251#step:4:6)4
gpg: directory '/Users/runner/.gnupg' created
gpg: keyserver receive failed: No route to host
make: *** [/Users/runner/work/kuadrant-operator/kuadrant-operator/bin/operator-sdk] Error 2
Error: Process completed with exit code 2.

Example run:

This might be an issue with github actions mac os image itself but perhaps we should evaluate if we there is much value in keeping running the Test Scripts action for the mac-os platform since this error happens frequently
