Correction misinterpretation of Presentation Exchange for OpenID

[logangirvin]

Problem:
While adding support for multiple vp_token responses, changes were made to parsing requests to allow multiple presentation definitions in the open_id request and treat each presentation definition as an independent vp_token. This change was not within specification and should be removed.

Solution:
Removed support for multiple presentation_definition objects in open id requests.

Validation:
Manually validated against application code.

Type of change:

• Feature work
• Bug fix
• Documentation
• Engineering change
• Test
• Logging/Telemetry

Risk:

• High – Errors could cause MAJOR regression of many scenarios. (Example: new large features or high level infrastructure changes)
• Medium – Errors could cause regression of 1 or more scenarios. (Example: somewhat complex bug fixes, small new features)
• Small – No issues are expected. (Example: Very small bug fixes, string changes, or configuration settings changes)
