Closes#18207
This PR adds license status to support bundle to help with
troubleshooting license-related issues.
- `license-status.txt`, is added to the support bundle.
- it contains the same output as the `coder license list` command.
- license output formatter logic has been extracted into a separate
function.
- this allows it to be reused both in the `coder license list` cmd and
in the support bundle generation.
