Spring 7 - Jackson 3.x

[jdaugherty]

Issue description

Upgrade to Jackson 3.x - spring-projects/spring-framework#33798

[jdaugherty]

Some more information:

• Jackson 3 has a JDK17 minimum
• Groovy still uses Jackson 2 internally. We can still use Jackson 3, but Groovy's Toml & Yaml slurpers will still use Jackson 2.
