fix: add 4h task timeout in the ec pipeline

Since the default timeout for tasks is hardcoded to 1h/2h,
this change sets the timeout to a higher value to
support users who run bigger sets of images through
the verify task.

It is still possible to limit the duration of the check
on the pipeline or pipelineRun level, depending on usage.
