Add {m365_defender,microsoft_defender_endpoint}.vulnerability indices to kibana_system role permissions (elastic#132445) (elastic#132628)

Add logs-m365_defender.vulnerability-* and logs-microsoft_defender_endpoint.vulnerability-* data stream indices to the kibana_system's read privileges. This is required for the latest transform for 3rd party integrations CDR workflows (vulnerability findings) to work.

Also add delete_index on logs-m365_defender.vulnerability-* and logs-microsoft_defender_endpoint.vulnerability-* to facilitate index removal through ILM policies.

(cherry picked from commit 716bff8)
