• All tests passed. If this feature is not already covered by the tests, I added new tests.
• I used npm run format for formatting the code before submitting the pull request.

Description

allows other actions in a workflow to get at the token used to auth the CLI which is especially useful for OIDC auth

Solved problem

there isn't a way to get the token to use in other applications from the jf commands themselves, and the config is encrypted

Questions

1. what description would be appropriate for the output? i wasn't sure how to word all the cases where a token would/would not be returned.
2. what test can be added for this?
