Fix example test and test_fetcher for examples
# What does this PR do?

#16475 introduced a failure in the example tests that went undetected because the test_fetcher had the wrong path for the example test. This PR fixes both.
Confirmed this fixes the oversight in `test_fetcher` and fixes the actual example since the example tests actually ran (and passed) here. Since this is a failure on master merging without review but happy to address comments in a follow-up PR!<|||||>_The documentation is not available anymore as the PR was closed or merged._
