Upgrade to Jackson Bom 3.0.3

There is no need to ask for a dependency upgrade.

As mentioned in our issue template:

You DO NOT need to raise an issue for a managed dependency version upgrade as there's a semi-automatic process for checking managed dependencies for new versions before a release.

We will perform upgrades matching our 3rd party upgrade policy.
If this is an urgent matter for you, there is no need to wait for us releasing as you can use a Gradle or Maven build property to override the library version.
All version properties are listed in the reference documentation appendix.
