• Added K8s unit test jobs for the 1.35 branch for the ppc64le provider.
• Updated jobs for releases 1.33 and 1.34 to ensure consistency.
• Added fork-per-release and fork-per-release-cron annotations.
• Configured jobs to be automatically generated for future releases using config-forker and config-rotator if needed.

Hi @varshadeshmane92. Thanks for your PR.

I'm waiting for a github.com member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

@upodroid Your opinion on this please?

[upodroid]

Please create a release job for every supported branch. As of this message, 1.32 is supported, but it will be EoL in just over 2 months. The good news is that your job gets added to a shared file that will be dropped by sig-release at the end of the support window, along with everyone else's 1.32 jobs.
