Replace Supported Versions Logic with Ignore Versions in perfRegressionParallelPipelinebyRegion

We need to update the approach in `vars/perfRegressionParallelPipelinebyRegion.groovy` for handling the `versions` parameter (per test).
Currently, we maintain a list of supported versions.
This logic should be replaced with an “ignore versions” mechanism, introduced originally to skip tablet test cases for versions older than 2025.1.
