/**
 * A utility class that normalizes a Template object to simplify template comparisons in tests.
 *
 * The fromTemplate() method works by applying replacements for specific values with a
 * placeholder value. This is particularly useful because elements like the S3
 * keys for Lambda code assets include hash strings that change with every dependency update. Normalizing
 * these values prevents false negatives during template object comparisons.
 *
 * Current replacements:
 * - SHA-256 hash strings (64 alphanumeric characters) are replaced with 'dummy-cdk-asset'.
 * - Tags with Key 'dd_cdk_construct' are replaced with 'dummy-datadog-version'.
 * - LatestNodeRuntimeMap with 'dummyKey': 'dummyValue'
 * @example
 *   const appStack = new AppStack()
 *   const template = Template.fromStack(appStack);
 *   expect(NormalizedTemplate.from(template).toMatchSnapshot();
