Description of problem:
taskRuns deletion taking more time than specified in ttlSecondsAfterFinished in tektonpruner config
Prerequisites (if any, like setup, operators/versions):
**
- Install 1.21 OSP
- Disable old pruner & enable tektonpruner
- Create a new test namespace for testing taskRuns pruning
Steps to Reproduce
- Keep ttlSecondsAfterFinished to 30s in tektonpruner config
tektonpruner:
disabled: false
global-config:
enforcedConfigLevel: global
historyLimit: 100
ttlSecondsAfterFinished: 30
options: {}
- Create task & taskRun files attached below
[^task-for-pruner.yaml]
[^taskrun-for-pruner.yaml]
Actual results:
TaskRuns are taking more than the configured time to be cleaned up

Expected results:
TaskRuns should be cleared after ttlSecondsAfterFinished time is completed and the taskRun is succeeded.
