docs: clarify config tables, fix typos, and align JSDoc examples - #3456

Note

Low Risk
Docs and comment-only changes; no runtime or API behavior changes.

Overview
Documentation and JSDoc are updated so cluster and sentinel configuration matches what the client already supports, and a few doc mistakes are fixed.

Cluster (clustering.md) and sentinel (sentinel.md) option tables now list keyPrefix, commandOptions, and clientSideCache, with links to the shared guides. The cluster table also documents topologyRefreshOnReconnectionAttemptStrategy. Client configuration and pool pages use relative ./pool.md links instead of full GitHub URLs, with small grammar fixes on isolationPoolOptions and the pooling blurb.

Command options fixes the ASAP queue typo (“to send”) and shows timeout in withCommandOptions examples. Pool simple-usage examples call pool.ping() instead of incorrectly using client.

In TypeScript JSDoc for clientSideCache on cluster and sentinel, copy that referred to “pooled mode” is corrected to cluster/sentinel semantics, and examples use createCluster / createSentinel with rootNodes or sentinelRootNodes instead of pool-only options like minimum.
