PlanDefinition appear to require a library to bundle

[guptava]

Describe the bug
When trying to process a PlanDefiniton it appears that the tooling is requiring to have a library while the R4 profile does not require it. Once a library is added the error seems to go away and the PD is included in the bundle.
To Reproduce
Steps to reproduce the behavior:

1. Save a PlanDefinition resource without a library
2. Run the bash _refresh.sh tooling and receive an error

Expected behavior
For the PlanDefinition to be processed when it does not have a library.

Desktop (please complete the following information):

• Tooling version: 3.3.0
• OS: MacOS 12.6.8
• Java Version 9
