AWS CloudFormation integration deployment method — known issue for 9.2.x and serverless (#3947)

Addresses /issues/3946 by adding a known issue to
the serverless and stack docs.

Will update the serverless known issues again when the fix is released
next week, and close #3946 then.

+:::{dropdown} Deploying integrations using AWS CloudFormation doesn't work
+New deployments of integrations that collect data from cloud service providers, such as Asset Discovery and Cloud Security Posture Management, do not work when deployed to AWS using agent-based deployment and the AWS CloudFormation deployment option. The problem results from a malformed CloudFormation parameter: `ElasticAgentVersion`. The default value for `ElasticAgentVersion` has a space instead of a `+`. This produces an invalid agent version value.

+For more information, check [#14627](https://github.com/elastic/kibana/pull/242365).

+To work around this issue, update the default CloudFormation template by replacing the space in the `ElasticAgentVersion` parameter with a `+`.
