Can this be used to install conftest ? If not, is there a plan for an official action

Hi all,

I noticed that there are a number of conftest actions out there

https://github.com/marketplace/actions/conftest - instrumenta/conftest-action
https://github.com/marketplace/actions/conftest-action - YubicoLabs/action-conftest
https://github.com/marketplace/actions/setup-opa-conftest - princespaghetti/setup-conftest
https://github.com/marketplace/actions/conftest-opa-test-runner - ibiqlik/conftest-action-docker

In light of the recent tj-actions incident, it would be good to have an official conftest action, if this action cannot be used to install conftest since so many unofficial actions seem to be published.

Workaround

      - name: Install Conftest
        run: |
          curl -sSL https://github.com/open-policy-agent/conftest/releases/download/v0.55.0/conftest_0.55.0_Linux_x86_64.tar.gz -o conftest.tar.gz
          tar -xzvf conftest.tar.gz -C /usr/local/bin/
          chmod +x /usr/local/bin/conftest
          rm conftest.tar.gz

The issue does not name a file, test, or entry point. Start by reviewing the setup-opa action's TypeScript entry point and existing workflow behavior, then establish whether it can install conftest and define what an official conftest action would need to provide.
