Support token with jira-report

### New feature, improvement proposal

jira-report auth regression in the 3.x milestone

The auth support in the jira-report has room for improvement. Similar to #86 the jira-report should be changed to support tokens only. Atlassian has similarly [deprecated](https://developer.atlassian.com/cloud/confluence/deprecation-notice-basic-auth/) basic auth.

This looks to no longer be true, auth can be required on this endpoint.

The client setup looks to have removed the maintain session context when uplifted. Which if the report is changed to token only, would no longer be relevant.

Inizia con l’autenticazione e la configurazione del client in src/main/java/org/apache/maven/plugins/changes/jira/RestJiraDownloader.java intorno alle righe 415–420 e 753, quindi confronta l’implementazione precedente collegata nell’issue. Traccia il modo in cui jira-report esegue attualmente l’autenticazione e identifica i controlli di progetto pertinenti. Il lavoro è completato quando il report supporta l’autenticazione con il solo token senza dipendere dal contesto maintain-session rimosso.

Scritto dal modello di indicizzazione a partire dal testo della issue.
