Use Apache archive for Tomcat smoke test

[AlexeyKuznetsov-DD]

What Does This Do

Use the Apache archive to download the pinned Tomcat 9.0.120 distribution for the Spring Boot Tomcat smoke test.

Motivation

Keep the pinned Tomcat distribution consistently resolvable.

Additional Notes

The Gradle dependency update workflow could no longer resolve Tomcat 9.0.120 from dlcdn.apache.org:

Could not find tomcat:tomcat-9:9.0.120.
Searched in:
  https://dlcdn.apache.org/tomcat/tomcat-9/v9.0.120/bin/apache-tomcat-9.0.120.zip

dlcdn.apache.org only retains the latest Tomcat release. It currently serves 9.0.121, so the pinned 9.0.120 distribution has been removed. A fixed version can therefore become unavailable whenever a newer Tomcat version replaces it on the download CDN.

archive.apache.org is operational again and retains all published Tomcat versions, including 9.0.120. Using the archive keeps the pinned smoke-test dependency resolvable across future Tomcat releases without changing the locked version.

This addresses the recurring failure pattern previously handled by version bumps in #11091 and #12221.

Validation:

• ./gradlew :dd-smoke-tests:springboot-tomcat:resolveAndLockAll --write-locks
• ./gradlew :dd-smoke-tests:springboot-tomcat:unzip :dd-smoke-tests:springboot-tomcat:spotlessCheck

More details

The new Ivy base URL and the existing artifact pattern make the Apache archive path for Tomcat 9.0.120. This path keeps the fixed smoke-test version available after the CDN removes it.
