chore(renovate): pin jackson-annotations to 2.x and group tools.jackson

Jackson 3 uses the 2.x annotations (its BOM manages them at 2.22), and Maven
Central's newest com.fasterxml.jackson.core:jackson-annotations is 3.0-rc5, a
release candidate that sorts above every 2.x. allowedVersions keeps Renovate
from offering it. The Jackson group rule also matches tools.jackson now, so the
Jackson 3 jars still update together.
