Sometimes there will be no dynamic jobs,
like if there's no diff against main.
So show a more helpful message,
instead of
Success! You can now run the dynamic config jobs

When there's an error in the generated dynamic config,
sometimes the only way to fix it is to
delete that config.
Then, the user can rerun the setup job.
Maybe LCI should do that for them,
but that might be overstepping.

There would still be a problem running a
job in a config that doesn't exist,
but that probably isn't the place to fix it.
