chore(updatecli): Use the native temurin source

[gounthar]

• Enhanced JDK version bumping configurations for JDK 17 and JDK 21 thanks to the native temurin source
• Removed outdated script for JDK verification to streamline processes.

Testing done

updatecli diff --debug --config ./updatecli/updatecli.d/jdk17.yaml --values ./updatecli/values.github-action.yaml 2>&1
updatecli diff --debug --config ./updatecli/updatecli.d/jdk21.yaml --values ./updatecli/values.github-action.yaml 2>&1

Submitter checklist

• Make sure you are opening from a topic/feature/bugfix branch (right side) and not your main branch!
• Ensure that the pull request title represents the desired changelog entry
• Please describe what you did
• Link to relevant issues in GitHub or Jira
• Link to relevant pull requests, esp. upstream and downstream changes
• Ensure you have provided tests - that demonstrates feature works or fixes the issue

✔ Bump JDK17 version:
	Source:
		✔ [lastVersion] Get the latest Adoptium JDK17 version via the API
	Condition:
		✔ [checkTemurinAllReleases] Check if the "<lastVersion>" is available for all platforms
	Target:
		✔ [setJDK17VersionAlpine] Bump JDK17 default ARG version on Alpine Dockerfile
		✔ [setJDK17VersionDebian] Bump JDK17 default ARG version on Debian Dockerfile
		✔ [setJDK17VersionDockerBake] Bump JDK17 version for Linux images in the docker-bake.hcl file


✔ Bump JDK21 version for all Linux images:
	Source:
		✔ [latestJDK21Version] Get the latest Adoptium JDK21 version via the API
	Condition:
		✔ [checkTemurinAllReleases] Check if the "<latestJDK21Version>" is available for all platforms
	Target:
		✔ [setJDK21VersionDockerBake] Bump JDK21 version for Linux images in the docker-bake.hcl file

• Twin of chore(updatecli): Uses the native temurin source docker#1957
• Failure in the updatecli check is unrelated to this change! (it is the UBI9 stuff)

=> great work!
