Use kubectl create instead of apply

When running YAML E2E tests, use kubectl create instead of apply,
so that example can use generateName, which is a best practice
for run objects (TaskRun/PipelineRun).

Using "create" also exposed name conflicts for several secrets
all named the same. Luckily the content of those secret was the
same, so we had no race condition in the past, but it's best
to avoid side effects between tests as much as possible and
keep resource names uniques across examples.

Fixes #1397
