      Description of problem:

      doc "Managing custom catalogs" is not correct

      Version-Release number of selected component (if applicable):


      How reproducible:


      Steps to Reproduce:

      1.Create a Dockerfile that can build a catalog image
      should use bellow command
      opm generate dockerfile <operator_name>
      2. Example <operator_name>-index.Dockerfile is not correct, shuld be like bellow
      # The base image is expected to contain
      # /bin/opm (with a serve subcommand) and /bin/grpc_health_probe
      FROM quay.io/operator-framework/opm:latest
      # Configure the entrypoint and command
      ENTRYPOINT ["/bin/opm"]
      CMD ["serve", "/configs", "--cache-dir=/tmp/cache"]
      # Copy declarative config root into image at /configs and pre-populate serve cache
      ADD catalog /configs
      RUN ["/bin/opm", "serve", "/configs", "--cache-dir=/tmp/cache", "--cache-only"]
      # Set DC-specific label for the location of the DC root directory
      # in the image
      LABEL operators.operatorframework.io.index.configs.v1=/configs

      Actual results:

      opm validate passes successfully, but the pod for the index fails with:
      Error: compute digest: compute hash: write tar: stat .: os: DirFS with empty root

      Expected results:

      Catalog is served successfully.

      Additional info:

      Acceptance criteria:
      The opm CLI generates a differently-formatted Dockerfile in OCP 4.12, per https://github.com/operator-framework/operator-registry/pull/1033. Previously, the docs were providing an example Dockerfile because the "generate dockerfile" command was still in alpha. However, the command was graduated out of alpha via https://github.com/operator-framework/operator-registry/pull/902, which made it downstream starting with OCP 4.11, so the procedure can switch to using that command instead.
      The CLI reference docs can also be updated for the now-GA "generate" subcommands: https://docs.openshift.com/container-platform/4.12/cli_reference/opm/cli-opm-ref.html
      Backport changes to 4.11, as well.
