Update jackson-datatype-* to 2.21.0 and introduce JACKSON_VERSION

[xerial-bot]

About this PR

• Bump both jackson-datatype-json-org and jackson-datatype-jdk8 to 2.21.0
• Introduce JACKSON_VERSION val so future Jackson bumps update both deps in one place (these need to stay in sync)

Supersedes #4086 (older 2.20.1 bump).

This branch was rebased onto main after #4150 merged.

Code Review

This pull request updates the com.fasterxml.jackson.datatype:jackson-datatype-jdk8 dependency from 2.18.5 to 2.21.0. While this is a straightforward version bump, I've noticed that another module from the same group, jackson-datatype-json-org, is not being updated. This could lead to classpath issues. I've added a comment to recommend aligning the versions of all related Jackson modules and suggested using a variable to manage the version centrally.

[gemini-code-assist]

The jackson-datatype-json-org dependency on the previous line is still using version 2.18.5. It is highly recommended to align the versions of all modules from the com.fasterxml.jackson.datatype group to avoid potential classpath conflicts and ensure compatibility. Please consider updating jackson-datatype-json-org to 2.21.0 as well.

To make future updates easier and ensure consistency, you could define a variable for the Jackson version and use it for all related modules:

val JACKSON_DATATYPE_VERSION = "2.21.0"
// ...
"com.fasterxml.jackson.datatype" % "jackson-datatype-json-org" % JACKSON_DATATYPE_VERSION % Provided,
"com.fasterxml.jackson.datatype" % "jackson-datatype-jdk8"     % JACKSON_DATATYPE_VERSION % Provided,
