[Request]: Add more context in the create SLO permission

[kdelemme]

Description

The current documentation for the requested privileges for the SLO product is using logs-* in the screenshot. Some people might think this is required to work even if the 4th step mentions "any indices".
It could be useful to add something along this line: "in the below screenshot, we used logs-* as an example of such index."
