Subject: [PATCH] [Island Browser] - Fix Cannot execute ILM policy delete step
 (#134636)

This PR focuses on the short term solution which add the logs-island_browser.user-* and
logs-island_browser.device-* indices under the kibana_system role with deletion privileges
to prevent a failed deletion error when the index enters the deletion phase for the ILM lifecycle,
in upcoming PR. As it ships transform pipeline too hence read, write permissions are also required.

(cherry picked from commit ae63901a38f0c364782b0901b7e0f22eb020b4b3)
