* chore: add examples for new JS config options, other minor cleanups

This commit adds a "config-and-error-handling" page for the node.js
SDK, and in there we show some examples of how to use the succinct
version of the constructor without specifying an explicit config.
We also show an example of using the new `WithThrowOnErrors` configuration
option.

Also did a few other cleanups while I was in here, including:

* add missing example code for Lambda configuration on Configurations page.
* Remove all the "COMING SOON"s
* Fixed the order of the `TopicClient` example on the topics API reference page.
* Removed some redundant copies of stuff like 'observability' that was duplicated
  between "Topics" and "Cache" sections; but then gave up on this in favor of
  moving the "SDKs" stuff up to the top level in a subsequent PR after discussion
  with Allen.

 `Configurations.Lambda` is a configuration that is available in some SDKs, and is optimized for the AWS Lambda environment. It has configuration settings designed to pre-warm the client on Lambda function cold starts, and to ensure the connection is re-established proactively if a Lambda function remains idle long enough for the connection to time out.

+# How to Manage Configuration and Error Handling in the Momento Node.js SDK
+
+The code below illustrates the simplest way to construct a `CacheClient`:
+
+<SdkExampleCodeBlock language={'javascript'} snippetId={'configuration_ConstructWithNoConfig'} />
+
+However, you may pass in a `Configuration` object to customize the behavior.
+
+Momento provides several pre-built configurations in the `Configurations` module, such as `InRegion` (which is configured
+with timeouts and connection counts that are appropriate for server-side connectivity from within the same AWS region),
+and `Lambda` (which is tuned for use in AWS Lambda environments). Here is how you can specify the `Lambda` configuration:
+
+<SdkExampleCodeBlock language={'javascript'} snippetId={'configuration_ConstructWithLambdaConfig'} />
+
+:::tip
+If you omit the configuration, Momento will use the `Laptop` configuration by default. This configuration has relaxed
+timeouts, suitable for development or in high-latency environments. (It is not recommended for production, server-side use.)
+:::
+
+For more information about `Configuration` objects see [SDK Configuration Objects](/cache/develop/basics/client-configuration-objects.md).
+
+By default, `CacheClient` errors are surfaced to developers as part of the return values of the calls, as opposed to throwing
+exceptions. This makes errors more visible when you're writing your code, and allows your IDE to be more helpful in ensuring
+you've handled the errors you care about.
+
+Here's an example of how to check for errors on a `get` call:
+
+<SdkExampleCodeBlock language={'javascript'} snippetId={'configuration_ErrorHandlingHitMiss'} />
+
+However, if you prefer for exceptions to be thrown, you can configure the `CacheClient` to do so:
+
+<SdkExampleCodeBlock language={'javascript'} snippetId={'configuration_ConstructWithThrowOnErrorsConfig'} />
+
+With this configuration setting, any errors that occur will result in an instance of `SdkError` being thrown. You may
+catch it and use its `.errorCode()` method to determine the specific error that occurred:
+
+<SdkExampleCodeBlock language={'javascript'} snippetId={'configuration_ErrorHandlingExceptionErrorCode'} />
+
+For more information about error handling in Momento see [SDK Error Handling](/cache/develop/basics/error-handling-production-readiness.md).
