Upgrade Jackson to 2.21.1 to fix async parser DoS vulnerability

Fixes Dependabot alert #1 (GHSA-72hv-8253-57qq): jackson-core async
parser bypasses maxNumberLength constraint, allowing DoS via excessive
memory/CPU consumption with arbitrarily long numbers.

Upgrades:
- jackson-databind: 2.20.1 -> 2.21.1
- jackson-annotations: 2.20 -> 2.21
- jackson-datatype-jsr310: 2.20.1 -> 2.21.1
