Improvement for CICD acceptance tests

[littlejo]

My code is:

      - uses: opentofu/setup-opentofu@v1
        with:
          tofu_wrapper: false
      - run: go mod download
      - env:
          TF_ACC: "1"
          TF_ACC_PROVIDER_NAMESPACE: "hashicorp"
          TF_ACC_PROVIDER_HOST: "registry.opentofu.org"
        run: TF_ACC_TERRAFORM_PATH=$(which tofu) go test -v -cover ./cilium
        timeout-minutes: 10

Could you create automatically the environment variables?

Like that, my code would be clean:

      - uses: opentofu/setup-opentofu@v1
        with:
          tofu_wrapper: false
          acceptance_test: true
      - run: go mod download
      - run: go test -v -cover ./cilium
        timeout-minutes: 10

Hey @littlejo thank you for this issue, we discussed it with the core team and would be open for a community PR to resolve this with the addition that the flag should be called provider_acceptance_test for clarity.
