SpringBoot JDK upgrades check is failing on CI

Probably due to the recent change to the Liberica API:

jq: error (at <stdin>:1): Cannot check whether string has a string key
Script exited with error 5 on line 39

Might have been a flake. https://ci.spring.io/teams/spring-boot/pipelines/spring-boot-2.6.x/jobs/detect-jdk-updates/builds/63 was OK.

It's failing on this for me

milestone_response=$( curl -s https://api.github.com/repos/${GITHUB_ORGANIZATION}/${GITHUB_REPO}/milestones\?state\=open )

Makes sense considering those keys aren't set in my environment. I've set them and it worked so it looks like a flake after all, yes.
