[DOCS] Update audit-settings.asciidoc (#61610) (#61646)

* Update audit-settings.asciidoc

"I think" all {ess-icon} should be replaced by {ece-icon} because:
- audit logging is not allowed on ESS, as per https://www.elastic.co/guide/en/cloud/current/ec-add-user-settings.html and https://www.elastic.co/guide/en/cloud/current/ec-restrictions.html#ec-restrictions-security
- audit logging is allowed setting on ECE, as per https://www.elastic.co/guide/en/cloud-enterprise/current/ece-enable-auditing.html

* Removing ESS icons for audit settings
