This build _never_ declared (either directly or through
`platform_properties`) that it required the Java JDK, and appears to
have been "accidentally" getting it installed via a (now expired) cache
of the Java JDK.

Code Review

This pull request adds OpenJDK 21 as a dependency for the Linux analyze CI job. My review focuses on ensuring the stability and reproducibility of the build environment, which is particularly important for a stable branch. I've added one comment regarding the versioning of the new dependency to improve build hermeticity.

[
{"dependency": "ktlint", "version": "version_1_5_0"}
{"dependency": "ktlint", "version": "version_1_5_0"},
{"dependency": "open_jdk", "version": "version:21"}

The OpenJDK dependency uses the version tag version:21. This tag might resolve to different minor or patch versions of JDK 21 over time, which could lead to non-reproducible builds. On a stable branch, it's generally safer to pin dependencies to a specific version to ensure hermetic builds.

Consider using a more specific version tag (e.g., version:21.0.2) or a CIPD instance ID if available, to ensure that the same JDK version is always used.
