Adding feature flag for Job Summaries.

In order to disable the creation of job summaries,job-summary-enabled attribute can be provided the the setup CLI. default value is true.

example:

- uses: jfrog/setup-jfrog-cli@v4
  with:
    job-summary-enabled: false

Under the hood -

In order to avoid changes in the CLI itself, when the path of the output dir is not defined the CLI will ignore the recording of commands. Therefore, when the feature flag is disabled it will just make sure to unset the output dir path.
