2.0.0 orb is broken and should be flagged more obviously

**Orb Version**
2.0.0

**Describe the bug**
CircleCI started throwing this error even though we did not upgrade to 2.0.1. It fixed itself once we upgraded the orb, but there was no indication anywhere that the upgrade was a breaking change on previous orb versions.
```
bash: line 1: syntax error near unexpected token `newline'
bash: line 1: `'
```

**To Reproduce**
Have orb 2.0.0 as before and run the workflow to completion.

**Expected behavior**
It should not break, or people should be appropriately warned to upgrade.

No files, tests, or entry points are named. Start by examining the orb's 2.0.0 and 2.0.1 configuration or release information and reproduce the workflow behavior; done should mean the breakage is prevented or users are clearly warned to upgrade.
