[Bug] Examples workflow incorrectly passes

[joshichaitanya3]

Describe the bug examples.py doesn’t catch for the case when it cannot run the morpho file itself, as is happening right now since the command is morpho5. So no examples are run, but it reports all passing. While changing it to morpho6 should do the trick for now, it would be great to catch and report this locally or through the CI.

P.S. The examples.py is currently passing all tests if run with morpho6 on my machine!
