### Description

The [bootstrap checks docs for 8.1](https://github.com/elastic/elasticsearch/blob/8.1/docs/reference/setup/bootstrap-checks.asciidoc#system-call-filter-check) still have a [section for disabling system call filters](https://www.elastic.co/guide/en/elasticsearch/reference/8.1/_system_call_filter_check.html) even though that setting was removed in 8.0 (#72848) and its removal is [listed in the breaking changes](https://www.elastic.co/guide/en/elastic-stack/8.0/elasticsearch-breaking-changes.html)
