Readme `Input` section does not have `format` option

As the title. The Inputs section of readme does not have the format option listed.

I was curious if values are possible for format other than sarif, idk like sbom etc.

Late to the party and not being dismissive of the feedback, but for anyone else looking the easiest way to see it without installing kubescape and running kubescape scan -h is to look in the action.yml specification for the inputs.

  format:
    description: |
      Output format.

      Can take one or more formats. To use one format, omit the comma, e.g
      `format: json`. To produce results in multiple formats, separate them with
      a comma: `format: sarif,json`.

      For example, when using `output: "results"` and `format: "sarif,json"`,
      Kubescape will produce 2 files: `results.sarif` and `results.json`. You
      can then use `results.sarif` to publish results to Github Code Scanning
      and `results.json` to suggest automatic fixes.

      Run `kubescape scan -h` to see a list of supported formats.
