fix generating on-cel-expression in an 'on push' PipelineRun file

Currently, generated on-cel-expression would contain a path to a <component-name>-pull-request.yaml file in an 'on push' PipelineRun, which is not correct.
We need to determine between on-push and on-pull-request and adjust the filename in the on-cel-expression accordingly.
