"File 'ops.yml' does not exist" on "ops up" does not return non-zero exit status

[ErikHumphrey]

And maybe other similar errors.

Steps to reproduce

$ ops version
File 'ops.yml' does not exist.
1.17.0
$ cd /tmp
$ ops up && echo foo
File 'ops.yml' does not exist.
foo

Expected

For actions that require ops.yml to exist (example: ops up, non-example: ops version), return non-zero exit status.

This is fixed in crops.

The binary for Intel Mac is out of date, but next time I manage to build for that platform the fix will be included.
