To Reproduce

Steps to reproduce the behavior:

1. add PAT to keychain access -> Local Items, as described in configuration
2. export JIRA_AUTH_TYPE=bearer
3. without existing jira configuration run `jira init
4. you'll see 401 error

Expected behavior
init process is successful

Additional context
it works if the API key is in login chain though, so maybe just the configuration should be updated.
