fix(ci): bump @aws/agentcore-cdk to 0.1.0-alpha.18 and remove snapshot step from release (#850)

* fix(ci): bump @aws/agentcore-cdk to 0.1.0-alpha.18 and remove snapshot step from release

Sync the CDK template to the latest npm version and update the asset
snapshot. Remove the snapshot update step from the release workflow
since it runs the full test suite which requires uv.

* fix: use caret range for @aws/agentcore-cdk in CDK template

Use ^0.1.0-alpha.18 instead of pinning an exact version so new
releases are picked up automatically.
