Revert scalable monolithic to SSD (grafana#10958)

After consultation with @stevendungan, reverting the terminology
"Scalable monolithic deployment" back to "Simple scalable deployment."

Decided to add a note about the confusion that SSD causes to clarify
that we don't mean solid state drives.

FYI @monodot

 # Loki deployment modes
 
-Loki is a distributed system consisting of many microservices.  It also has a unique build model where all of those microservices exist within the same binary.
+Loki is a distributed system consisting of many microservices. It also has a unique build model where all of those microservices exist within the same binary.
 
 You can configure the behavior of the single binary with the `-target` command-line flag to specify which microservices will run on startup. You can further configure each of the components in the `loki.yaml` file.
 
 Because Loki decouples the data it stores from the software which ingests and queries it, you can easily redeploy a cluster under a different mode as your needs change, with minimal or no configuration changes.

-The scalable monolithic deployment mode, previously referred to as a simple scalable deployment (SSD), is the preferred way to deploy Loki for most installations. The scalable monolithic deployment is the default configuration installed by the [Loki Helm Chart]({{< relref "../setup/install/helm" >}}). This deployment mode is the easiest way to deploy Loki at scale. It strikes a balance between deploying in [monolithic mode](#monolithic-mode) or deploying each component as a [separate microservice](#microservices-mode).

-Loki’s scalable monolithic deployment mode separates execution paths into read, write, and backend targets. These targets can be scaled independently, letting you customize your Loki deployment to meet your business needs for log ingestion and log query so that your infrastructure costs better match how you use Loki.

 Monolithic mode is useful for getting started quickly to experiment with Loki, as well as for small read/write volumes of up to approximately 20GB per day.
 
-You can horizontally scale a monolithic mode deployment to more instances by using a shared object store, and by configuring the [`ring` section]({{< relref "../configure#common" >}}) of the `loki.yaml` file to share state between all instances, but the recommendation is to use scalable monolithic mode if you need to scale your deployment.

 You can configure high availability by running two Loki instances using `memberlist_config` configuration and a shared object store and setting the `replication_factor` to `3`. You route traffic to all the Loki instances in a round robin fashion.
