Issue # (if applicable)

The documentation for Stack#exportValue contains an “Example” section formatted as an H2 with two H3 sub-sections, whereas the method signature uses an H3.

When generating documentation for CDK libraries inheriting from Stack, and jsii duplicates this “Example” section for each stack in the application in the API.md, this formatting issue causes a disruption in the heading hierarchy. This is particularly problematic on constructs.dev, where H3 headings are listed in the sidebar. Examples can be seen at:

• https://constructs.dev/packages/@condensetech/cdk-constructs/v/0.1.2?lang=typescript
• https://constructs.dev/packages/@cloudcomponents/cdk-temp-stack/v/2.4.0?lang=typescript
• https://constructs.dev/packages/@gammarers/aws-lambda-function-invoke-error-notification-stack/v/1.0.49?lang=typescript

Reason for this change

By removing any heading from the method doc, there's no risk of altering the generated markdown hierarchy

Description of changes

I've removed the headings from the method documentation
