add heading for OpenSearch FS recommendation (#3085) 

adding a heading allows creating a deep-link directly to this
information, making it easier to direct others to it.
the note itself doesn't actually belong to the OS recommendation as it
has nothing to do with the OS it's running on.

We recommend installing OpenSearch on Red Hat Enterprise Linux (RHEL) or Debian-based Linux distributions that use [systemd](https://en.wikipedia.org/wiki/Systemd), such as CentOS, Amazon Linux 2, or Ubuntu Long-Term Support (LTS). OpenSearch should work on most Linux distributions, but we only test a handful. We recommend RHEL 7 or 8, CentOS 7 or 8, Amazon Linux 2, or Ubuntu 16.04, 18.04, or 20.04 for any version of OpenSearch. OpenSearch also supports Windows Server 2019.

## File system recommendations
Avoid using a network file system for node storage in a production workflow. Using a network file system for node storage can cause performance issues in your cluster due to factors such as network conditions (like latency or limited throughput) or read/write speeds. You should use solid-state drives (SSDs) installed on the host for node storage where possible. Avoid using a network file system for node storage in a production workflow.
