[juralio-james]

An issue was found with the Spring security core plugin on the 22nd of November 2022

This is just a bump to the version used to prevent the plugin being affected.

Thanks,
James

Thank you for the pull request. We also need to update the publishing to Maven Central. I will try to get this resolved by this week.
