docs(assertions): update link to migration guide (#25602)

The link to the `@aws-cdk/assert` -> `aws-cdk-lib.assertions` migration guide was incorrect, and sent you to a 404 page. The migration guide only exists on the `v1-main` branch now, since the `@aws-cdk/assert` library is not published with v2. ---- *By submitting this pull request, I confirm that my contribution is made under the terms of the Apache-2.0 license*
