feat(ticket): update ticket metadata on change of incident type

[whitdog47]

This PR introduces a new feature that updates the metadata of a ticket whenever the incident type changes. This ensures that the ticket reflects the most accurate and relevant information, improving incident management and tracking.

Key Changes

1. Incident Service Update:

   • Modified the update function in src/dispatch/incident/service.py to include logic for updating ticket metadata when the incident type changes and contains plugin metadata. This is contingent on the project key of the ticket matching the new incident type's project key.

2. Plugin Interfaces:

   • Added update_metadata methods in src/dispatch/plugins/dispatch_core/plugin.py and src/dispatch/plugins/dispatch_jira/plugin.py. These methods are responsible for updating the metadata of the Jira ticket.

3. Ticket Flow Enhancements:

   • Implemented a new function update_incident_ticket_metadata in src/dispatch/ticket/flows.py. This function coordinates the metadata update process by:
     • Retrieving the appropriate ticket plugin instance.
     • Using the plugin to update the ticket's metadata with the new incident type details.
     • Logging an event to record the update.
